Gamo CF-X field test

by B.B. Pelletier

A Leapers 3-12x tactical mini-scope fits the CF-X with room to spare. B-Square high mounts give plenty of clearance.

The Gamo CF-X is a popular spring-piston rifle that I "tested" for you by surrogate on Friday, Jan. 6, of this year. I made some assumptions in that report. Now that I've tested an actual CF-X in the field, it's time to see how close I came. I mounted a Leapers 3-12x power compact tactical scope just for the CF-X guy to see how that scope works on the rifle. The scope rode in B-Square non adjustable 30mm rings with a B-Square scope stop placed behind the rear ring.

A first look at the rifle
The CF-X is a fixed-barrel underlever spring gun that uses a rotary breechblock to access the barrel for loading. Because this is a BSA design and because Gamo owns BSA, I assumed that the rotary breech would be similar to the one on the BSA SuperStar I shot years ago. The CF-X is a much smaller rifle with a narrower spring tube. It's also a bit lighter. In fact, I find the CF-X to be very light for all the power it has. I guessed that cocking would be smooth, and it is. The CF-X is the most refined powerplant Gamo has yet fielded. When it shoots, it's just as smooth - a fact I got wrong in the earlier report. I had thought there would be some twanginess to it, but the rifle I tested is quite smooth.

The trigger
The CF-X trigger is classic Gamo. It's extremely creepy with a long second stage pull. It takes a lot of getting used to. However, these triggers do wear in with time and will become crisper (or able to be adjusted to a crisper pull) after they have some time on them. To their credit, Gamo puts a manual safety on the gun. Once it's cocked, you're ready to go.

The rotary breech
I do not care for the rotary breech, but if it's necessary, I'll live with it. Round-nosed pellets tend to flip around backwards on the loading ramp, which takes time to sort out. I soon learned to load this rifle horizontally instead of resting the butt on my leg (like I usually do) because many pellets fell back out of the breech. The loading ramp on the CF-X is also not as smooth as the one on the BSA I tested, so this gun REALLY flips pellets if you're not careful!

The breechblock rotates to the left, revealing a groove that guides the pellet to the barrel.

All guns will vary; this is what I got with mine. RWS Hobby (7 grains) averaged 942 f.p.s. Crosman Premier light (7.9 grains) averaged 873 f.p.s. Beeman Kodiak (10.6 grains) averaged 785 f.p.s. The new Gamo Raptor (5 grains) averaged 1153 f.p.s. I notice that my velocities are only a few f.p.s. different than those of reader JB, which is encouraging.

I learned that the CF-X does not like heavy pellets! It threw Beeman Kodiaks and Crosman Premiers 10.5-grain pellets all over the place at the 33 yards I had the target placed. Group sizes of 2.5" to 3.5" were common at that range, which is way below acceptable accuracy for a gun in this price range. Then, I tried Crosman Premier lights - the pellet of choice for many spring gun competitors in field target. The groups climbed up on the target about three inches and shrank to less than 1.5" for five shots. I was onto something, but still shooting poorly.

None of the usual techniques worked!
Group after group was a heartbreaker, with three shots going into an American quarter and numbers four and five opening it up. I tried every technique I know, and even held the rifle firmly to see if that was the solution. It wasn't. I also tried something that usually doesn't work - I rested the gun DIRECTLY on a sandbag without a hand in between. Voila! The groups tightened by a third! My best group of the session at 33 yards was one that measures 0.886" - just over 3/4 of an inch. I shot enough similar-sized groups with this technique to know that this one is not a fluke.

While the CF-X is not in the TX200 class for accuracy, it's right there with most RWS Diana guns. I know I said yesterday that an RWS Diana 52 can almost keep all its shots on a dime at 30 yards, but I believe the CF-X can do it, too. With my limited test, all I did was establish that the gun can shoot - I have not pushed it as far as it will go. Just hand-sorting the pellets should eliminate another quarter-inch from the groups. And, who knows what the absolute best pellet may be? Discovering that requires an investment in range time.

Gamo Raptors!
I couldn't get Raptors to print on the target paper at 33 yards, so I backed up to 15 FEET and shot a couple. They were already beginning to disburse at that close range, so I knew they would be wildly inaccurate in this rifle. I then moved the target to 15 yards (45 feet) and proceeded to shoot a five-shot group that measured 1.065". At 33 yards, that would open to a four or five-inch group which is absurd. The Raptor is not a pellet for the CF-X. CF-X guy - if you want to shoot tin cans with them, make sure they're close.

My take on the Gamo CF-X? It's a heck of a lot of air rifle for the money! The action is tight and smooth and the rifle is light and very easy to cock. The trigger is the worst feature, but it's one of the better Gamo triggers I've seen (and we know it gets better with use). The rifle is surprisingly accurate, and I will be recommending it to a lot of new shooters. The Leapers scope and B-Square mounts made this test very easy and pleasurable.

BB I like the three pellet test (and the specific ones you chose for it). It should be an industry standard!

Thanks for two excellent pieces, one on the RWS 52. I suspect in response to my earlier comment on the gun and the present piece on the CFX. I am a newbie to air guns and when I bought the 52, I had read that these guns are very responsive to the pellets used by both weight and brand and with the more powerful spring guns, you want to keep the velocity well under Mach 1 (1100 fps); consequently, I bought a variety of pellets to try out. After reading both yesterday’s and today’s piece, I may well have over bought my selection of pellets and your response to the following list of pellets may well be beneficial to other readers. I will list what I bought and perhaps you can suggest what was un-necessary, or perhaps potentially damaging to the RWS 52. Crossman Copperheads (7.9gr), RWS Pellet Sampler Package. A Korean off brand that came with the rifle “Cobra” (13.1gr), H&N Baracuda Match (10.65 gr ), Beeman Silver Arrow (11.5 gr), Crossman Premier Heavy (10.9gr), Gamo Sampler Pack (of 4 different pellets), finally, I may have gone overboard and bought Eun Jin (16.1 gr). First question is have I over done it with the heavy pellets? Some of these are very heavy for a 177 and can they damage the gun? So far I have been using the Copperheads, Premier (Heavy), and Gamo Match. The best accuracy is (10 Yards) with Crossman Premier (Heavy). I need to also say, I am not a hunter, and all I do is punch holes I paper with the intent of becoming a better shot with my other firearms. I am also the guy who asked about the IZH 46M a while ago and I bought that as well following your comments. Finally, I have been using the 22 cal bullet trap and it has worked very well with the RWS 52. I would urge anyone looking for a trap to use in the house with one of the more powerful air guns, to consider a 22 cal trap, not a trap designed essentially for pellets.

Thank you for such a detailed comment. You know, it's been several years since I really tested a .177 RWS 52, but I do know that those who shoot it in field target matches use the Crosman Premier light (7.9-grain) pellet. In fact, remembering that wasa what prompted me to try them in the CF-X. Now the 52 is a good bit more powerful than a CF-X, and the Premiers will be going pretty fast, but I would give them a try.

I do not believe heavy pellets will damage spring guns. That's contrary to what a lot of shooters think, but I've never seen any evidence to support that they do.

And, YES, to the bullet trap!

Hi BB,

Earlier I asked about scoping a BS 392 and you asked for a report. I've since thought better of the whole thing. The Williams peep works well enough to avoid the risk and expense of a scope experiment gone bad.

I would like to mention pellet traps. I've been using the Cone Pellet Trap by GAMO for months and have quite an investment in paper targets for it. It's falling apart just from using my 392 at no closer than 10 yards and further. The spot welds on the bottom cap of the dead-pellet well gave loose so I "glued" it with a metal epoxy and it's been holding. But I've noticed that the top and sides of the funnel are bulging due to pellet impact and I'm getting concerned it may fail, so I'm thinking about a replacement.

PyrmyrdAir advertizes the Gamo trap with a "lifetime warranty" printed right on the web page, but I like the idea of the trap mentioned by PCR suitable for .22 bullets. Thoughts?

Love the information exchange here!

(airgun legal) country in the world except U.S. & Canada. What would be the issues, if

any, of driving into Mexico, buying one and bringing it back into country?

The pellets aren't so fiddly to load on the .22, which is one reason I got it rather than a .177

The CFX Royal in .22 likes H&N FTT pellets -- label on the underside of their tin says they are 5.54
So does the 440.
Re the question on noise - (at UK non-FAC power limit) the CFX is noticeably noisier than the same-power Gamo 440, though not excessively so. Both at their quietest if fed their favourite pellets.

Hi BB:

After reading all the admonitions against gripping the forend or the pistol grip, or pulling the stock into one's shoulder, I can't help wondering how one is to obtain any accuracy from the off-hand hunter's stance. I have no way to set up a shooting bench, so all my shooting necessarily is off-hand or sitting. I seem to be hitting the target OK, but I'm certainly not punching dime-size groups, let alone one-holers, nor expecting to.

I'd like to know what sort of groups a modest off-hand shot could expect from the various rifles and pellets you test. I realize that would introduce an unpredictable variable into the test, but some sort of benchmark might be welcome to others who don't shoot from rests.

Hunters can rest the forearm on the flat of their hand rested on a knee, or the back of an arm braced against a tree. But like I said in the report, the CF-X doesn't act the way most other springers do. So I'd say you need to experiment to find the best hold.

CF-X guy,

The CF-X trigger isn't painted - it's blued, which is really black oxide. So if you've worn it off that soon you must have extra-acidic hands.

No paint will work for this. You may have to do some touchup with a cold blue. Look at Webley Gun Blue.

On the post you said that the cf-x throws the kodiaks all over the place.Then you said you shoot it resting it in a sandbag wich is rare but I tried it on mine and got much better accuracy.Also try a hard grip and I got better accuracy.I want to know ,
if you shoot the cf-x with the right technic,will you be able to get accurate shoots and good groups with the kodiaks?

Jason, AirGunDoc,

Appreciate your comments on the 392 scope and the pellet trap. Definitely time to retire this trap I'm using.

I've been rethinking this idea of scoping my 392 and will probably kick it around some more before putting it to rest. My peep sight works as well as my older eyes will allow so I'm torn. Jason, I'll find your comments give it some more thought.

The Williams peep sights are wonderful and a lot of people use them instead of a scope. The great thing is if you have the peep sight and a scope w/ mount you can always change between them. The best of both worlds! Thanks,

My CF-X seems to like the Gamo hunter pellets best. I put one of Charlie Tuna's GTX triggers on it and what a fantastic improvement. Trigger pull is smooth, crisp and light. Installation is a simple 15min. job. One question though, how do you clean the barrel? Seems like the rotary breech is too much in the way to push a brush through.

At February 23, 2006 8:09 AM, Anonymous B.B. Pelletier said...


The Gamo rotary breech does make cleaning difficult. About all you can do with the CF-X is clean from the muzzle.

Fortunately, airgun barrels seldom need to be cleaned.

first of all thanks b.b. for all the great info. In reading post about the cf-x i noticed alote of same things with my 220 hunter. after about 3000 shots figered groups were not going to get any better although the triger did. after taking gun off the bench and trying off hand shots with a tighter grip all around. groupings seem to get smaller. back to the bench and 2000 more shots(motorcykel wreak = wheelchair for last 10months =lots of pratice)with rest just in front of trigger my best 3shot group at 10m is 1/4in and down to 1-1/2in from 3 to 4in at 65yds.mind you thats my personal best somedays better than others.now the good part yesterday the main spring broke about 1-1/2 or twp coils from the end.need a new spring any help would be greatful. thanks all jbyrd

I think you are ahead of me on the 220. And as for the mainspring, my experience has all been with other guns. To be honest, yours is the first Gamo spring break I've heard of.

I can tell you this on the hold, however. A sensitive rifle will respond to WHERE on the stock you hold it. I always thought RWS rifles were the most sensitive and that Gamos were less sensitive.

Influenced by already having a CFX, and partly by BB's favourable reminiscences on the BSA, took a chance on buying it without having handled one before - and am very glad that I did!
The Superstar has quite superb balance, and seems less hold-critical than its Gamo successor.
If only the Leapers mini 3-12x44 IR mildot Scope was available in the UK, reckon it would be a perfect match.

Hi Guys,

Want to clean your CF-X ? Get a Hoppes Bore Snake made for .177 airguns, carefull... they make one for .17cal firearms. Get the airgun model it does NOT have the metal brush bristles!! The bore snake will fit into the barrel from the rotating breech if you shorten (hacksaw) the brass weight just a little. Go slow, cut a little & try, eventually it will slide right in( I cut mine too short, but it's still heavy enough to work). One or two passes with the bore snake should safely satisfy your cleaning urges!!

I know Pyramyd Air ships all around the world. And the credit card company will do the currency exchange. So you really don't need to suffer. I have no idea what tarrif or V.A.T. you might have to pay, but at the low price of the Leapers, you might still come out ahead.

Sadly, when looked it up on Pyramid Air the shipping cost was shown at around $60....
VAT in the UK is 17.5%.
May have to settle for a Bushnell Trophy 3-9x40 mildot instead; at 11.7 inches long it might just fit. It's either that or a non-illuminated 25mm tube Leapers (but AGS badged) mini 6x40 mildot that's less than half its price.

Hi we own 3 CFX Royals,

The only problem that I have picked up , if you dont seat the pellet properly they tend to hook the O ring on the breech and either pull it out or cut it. It is a simple repair but annoying.

I have found that a Gammo TS 10 (10.5 grain) works very well and the supprising thing with new O-ring it consistently tested at 969fps believe it or not. With the factory O-Ring in the other 2 rifle only read 879 fps on average

thank you for the wonderful review. I am currently going to purchase an adult air rifle here in canada and half narrowed the field to either the gamo varmit hunter or the cf-x. Wondering if you have an experience with the varmit hunter and which oneyou would recommend over the other.

About the same price shipped to my door for either one. Since this will be a varmit gun, synth stock is a must but formost is accuracy. I can later scope the cf-x if need be. Fancy addons look good but the gun must shoot well first :)

any help would be greatly appreciated

Your English is fine.

I have tested both the Gamo Shadow 1000 and the CF-X and I think the CF-X is more accurate.

The rotary breech can be difficult to load because the pellet flips over on the loading ramp and tries to enter the barrel backwards.

Both guns are good for the price, but I do like the CF-X best.

The CF-X I tested was not bad. For a Gamo, it was extremely good. A TX200 will outshoot it, but it will also outshoot any other spring rifle except a Whiscombe.

If you want a rifle that requires no technique to be accurate, you want a pneumatic. A PCP like the Talon from AirForce is a wondefrully accurate rifle that need not be held in any special way.

what scope would you say is the best top of the line scope for the cfx. Money is not an issue.

At September 07, 2006 6:18 AM, Anonymous B.B. Pelletier said...

The CF-X needs a shorter scope to allow loading room. I could recommend the Leupols Vari-X II, but the optics are not as clear and sharp as the Leapers scope shown on the gun in the picture above.

Because of the shorter scope limitation, A shot Leapers would be my recommendation.

I'm looking at spending $250 or under for a simple air rifle to kill some squirrels with. I've been looking at the CF-X Combo, and the Shadow Combo. I'm not going to be shooting at distances about 50-60 feet tops. Which gun should I get? Also, with that gun, which pellet should I use to best take down the squirrel in one shot?

To all Shooters

I purchased a Gamo CFX last year and found it to be a very impressive rifle.
Mine is .177 cal. Found the trigger creepy though. I modified the trigger by installing a lighter spring for first stage and made a 2mm (0.078") longer adjusment screw for second stage. The trigger can now be adjusted for a very crisp creepless lett off. I tested safety by cocking the rifle and bashing it a bit as this type of adjustment is very dangerous, so please be GAREFULL if attemted and watch that muzzle controll.

I managed a group of 10mm (0.39") at 20 meters (21 yards) with supplied open signts. This was with a prone position resting the rifle forend on a sponge. Found a loose hold to be most accurate.

It has been a bit since anyone posted on here, but I was just surfing the archives today and this caught my attention. The report says that the Gamo Raptor is NOT a good pellet for the CF-X, but I have had very good success with the pellet in my CF-X. I have killed several pest birds out at 30+ plus yards, and couple at 50 yards, and one at all the way out at 65 yards.
It could have been just a lucky shot, but I have had several of those "lucky" shots, so not inclined that way. But, I have had shots that missed when I was pretty sure they were going to score, so maybe it just flings them around, and every so many shots I get "lucky".
Just a few thoughts.

Well, I got a powerful .177 GAMO Varmint Hunter a week ago because of the (poor, but adequate) included BSA scope & laser sight/flash light combination made the buy seem like a good deal. I returned it immediately as the accuracy of the gun was “good”, but definitely not good enough. I then hooked myself up with a Winchester Summit 1000, as I was very attracted to the WAY better scope than the BSA combo that came with the GAMO Varmint Hunter, but the results were still about the same. Although the Summit 1000 seemed to be louder and a tad more powerful than the GAMO Varmint hunter, it was still unacceptable, accuracy wise. I think that the loudness of the Summit also psyched me to think that it was more powerful. NOT, The Varmint Hunter was. Anyway, I returned the Summit and ended up with the GAMO CFX as the fixed barrel was my incentive towards better accuracy. I was right. The GAMO CFX simply whooped butt over the other two rifles that I have tested. I shot all the rifles at 10 ~ 30 ~ 50 yards, fixed target(s), rifle(s) resting on stacked sandbags for near zero movement. Now concerning the GAMO Raptor pellets: When I sighted my rifles using these pellets, they were VERY accurate, fast and true. So, I really do not understand the negative write-ups with the Raptors. I simply must disagree. The other pellets that I have tried, (Lead: GAMO Match, Hunter, Magnum and Match points as well as the Crosman .177 hollow points) seemed to drift, in general, lower and sometimes to the right. Also, I found that the GAMO match pellets seemed to keep up, by less than a half an inch, in line of the Raptors which, like I said, I found to be the more accurate pellet if your rifle is properly sighted using them even though they are pricier. The CFX is definitely a very accurate rifle and for the price, is a great deal. I would go with a better scope that comes with the GAMO CFX, like the Crosman that comes with the Remington Summit 1000, a 4x32 Mini A.O. The Bug Buster, a 6x32 Mini Size A.O. Bug Buster 2, or a Leapers 3-12X44 30mm SWAT Mini Size a. There are most probably several other scopes that are better to use with the CFX than the one that came with it.

I have owned my Gamo CFX Combo with the BSA 2-7x32 scope for about 2 years now. I have found it to be a real tack driver at 20-30 yards, but also very capable of reaching out to 50 even 60 yards to bring down those gun wary Crows. For me I have had the best results loading up with RWS SuperPoint Extra's for fairly consistent accuracy with the occasional stray now n' then. What I have noticed is that keeping it pulled tight to the shoulder with a firm grip just in front of the scope rail on the back half of the front grips while keeping an easy grip with the trigger hand. Then take up the trigger stack and fire with a quick trigger pull.. Well, at lest that’s what works best for me anyway. .HEHE. . It couldn’t hurt. Give it a try, if it works for me it might work for you. But, yea I’m pretty pleased with my CFX. It packs a nice punch to, but these superpoints do tend to over penetrate quite a bit! Got any suggestions??

Hey guys, I have just one simple question I was hoping someone could answer. For use on the cf-x, I see that the leapers scope in the test had the B-square 11mm dovetail rings. If for example I wanted to use the bug buster/bug buster 2 scope, which rings would I buy for use on the cf-x with these scopes? Thanks for the help. =]


At December 02, 2006 12:21 PM, Blogger B.B. Pelletier said...


If you want non-adjustable rings, the A.G.E. 2-piece medium height airgun rings look good.


If you want adjustable rings, the 2-piece B-Square Interlock Adjustable rings look good.

Thanks for the quick reply B.B. One more quick question I have regarding these scopes. I'm a little indecisive about which one I'm going to purchase. the two in question are the Bug Buster 2, and the one you used in the field test. The price difference and and 3-yd minimum parallax setting makes the Bug Buster slightly more appealing to me, although I'm not sure if i'll even use it that close. Have you had any experience with the Bug Buster 2, and if not what do you feel really sets the scope from your test apart? I see the Leapers 3-12x has the variable magnification whereas the buster is a fixed 6. Other than this and the objective diameter, are there any durability differences between the two that you've heard of? I really just want something thats going to remain reliable through years of use. Thanks again.


At December 03, 2006 11:25 AM, Blogger B.B. Pelletier said...


The Bug Buster 2 is a fine scope. The biggest drawback is how difficult it is to mount because it is so short. The 12X scope used in the test is also very compact, but it's bigger than the Bug Buster. It does have brighter optics, which give you a 15-minute edge in the morning and evening, as far as hunting time goes. That's important to deer hunters, but not to squirrel hunters.

If the choie were mine, I'd get the Bug Buster.

Hey BB, I'm having a slight problem at the moment. I just opened my CFX and cleaned the "grease" if you will off the outside with some hoppes. Worked great, but I didnt think the inside of the barrel would have anything in it. Upon firing, smoke and a nasty smell came out. Any tips on what to do? Im sure hoppes would do a good job, I'm just having trouble finding something to go down through the barrel. Thanks in advance!

At December 06, 2006 5:40 AM, Blogger B.B. Pelletier said...

Keep Hoppes No. 9 out of all airguns! It attacks the seals.

Cleaning the CF-X is difficult because of how it works, but why do you have to? It can just be shot as is. The smoke you saw is normal and may or may not last awhile. Just shoot the gun.


At December 06, 2006 11:01 AM, Anonymous Anonymous said...

The product I used on the outside wasnt no.9. It was called Hoppes Elite foaming metal conditioner. Is this just as bad as the no.9? Hope using it on the outside wouldnt have messed it up, because a little may have gone around the breach.

I did a search but couldn't find the exact product you mention. However, the Elite series is formulated to remove metal fouling and that stuff is usually bad for synthetic seals.

At December 17, 2006 9:42 AM, Blogger B.B. Pelletier said...

If you over-oiled your guns or used pellets that are too light (7 grains for .177 and 12 grains for .22) then you might have had somthing to do with it, but I think not.

Both guns have mainsprings that are stressed to the maximum. They need medium weight lead pellets (8 grains in .177 and 14 grains in .22) to make the piston not smack the end of the compression chamber, setting up a wave of vibrations in the mainspring.

hello, I would like to know several things about this rifle, or any 1000 fps rifles in general.
I want to set up a shooting place in my backyard, (which isn't very big, 30-50 feet max range), but i want accuracy. I need a pellet trap to protect my wall, a big one, like home made out of cardboard or playwood or something. How much do you think it would take to stop a bullet from the cfx?

At December 22, 2006 1:26 PM, Blogger B.B. Pelletier said...

No wooden pellet trap is suitable for the CF-X. You need either steel (the Heavy duty trap that is now out of stock) or the Quiet Trap.

A 2 by 4 will stop pellet from the CF-X, but after 20 shots in the same place, they will shoot through. Since you will be shooting targets, count on them all hitting in the same place.


At December 28, 2006 3:28 PM, Anonymous The.Man said...


I'm confused. in reply to a comment above on the best pellet for the CF-X you said:

"3. I always recommend Beeman Kodiaks and JSB Exact pellets in both weights for the CF-X."

of those three, two of them are very heavy (10gr+). However, in the review, you said in bold "I learned that the CF-X does not like heavy pellets!"

So, which is it? I am poor and would like to purchase 4 cans of pellets but I need to know if I should get them heavy or medium or light. I know you're the man so I just need clarification! BTW, I will be killing small squirrels around my house....only, Thank you.

At December 28, 2006 3:39 PM, Blogger B.B. Pelletier said...


You were right to call me on this. I recommended those pellets without reading my own test. The CF-X I tested liked Crosman Premier 7.9-grain pellets the best. One box of them has 1,250 pellets, so it's like 2.5 boxes of anything else.

If you are buying three pellets to get the 4th free, I would also try the 7.6 grain JSB Diabolo Exacts, too.

I'm sorry for the mistake.


At December 28, 2006 3:50 PM, Anonymous The.Man said...

Thank you, no problem at all. I just wanted to make the most of my purchase. I was going to get a few different brands to test which seems easy to pick until you start throwing weights into the mix, before you know it you're up to twelve cans!

Also, the way the article flows, you switched pellets before sandbagging the CF-X (of course!)so I wasnt sure if you went through all the pellets again after sandbagging the rifle or not. You can only give so much detail in an article which is why all these comments are so valuable to us readers.



At December 28, 2006 4:07 PM, Blogger B.B. Pelletier said...


No, I didn't retest after sandbagging. But in all the testing I've done recently I note that lighter pellets often do perform best in springers.

i'm glad you did a review on the cf-x it's helped me make up my mind to buy one but... the scope, i can't decide.
i like the one you demo'd. the "3-12x44 30mm swat mini" and i also like the"6x32 mini bug buster2"
the bug buster Parallax setting is 3yards-infinity and the 3-12x44 is 10yards-infinity
i like them both which one would you recomend, and what mounting would you go with if you choose the bug buster? because you demo'd the b-square 30mmx11mm and it,s suggested to go with the 3/8 dovetail mount with the bug buster will this fit? thanks for your input.

At December 28, 2006 11:22 PM, Blogger rig said...

sorry b.b.
i just read some of the above comments and it looks like your going with the bug buster 2 as scope of choice

thanks again;

At December 29, 2006 6:47 AM, Blogger B.B. Pelletier said...


I can't recommend the Bug Buster for the CF-X. The BB is a short scope, and the CF-X has a recoil stop block positioned so far forward that the exit pupil will be off. You'll only see a small portion of the image from the BB.


At December 30, 2006 10:55 PM, Anonymous Anonymous said...


if the only reason for not liking the bug buster2 is that the built in scope stop is to far forward to use the scope properly why not just un scerw it and mount something like the b-square stop?
did you have this problem when you mounted the leapers mini swat? i remeber you saying if was thight to get on, or a tricky thing to mount.

thanks rig.

Did you ever find a grip that worked with the cf-x while in a standing position with a post or something to rest against? I'll be shooting squirrels from my balcony using the doorframe to rest against. Im getting mixed results at the range emulating this position with both loose and tight grips. In fact, I can only shoot 3/4 inch groups by resting it and touching nothing but the trigger @ 25 yrds. Of course, I cant sort pellets by weight which i think is a major factor. This brings me to my second question. What is the most affordable electronic scale you can reccomend with confidence? Thank you for your time.

In your situation I would try the gel shooting support Pyramyd sells. You'd rest it on the railing with the gun on top.

I have had a Cf-x for a while now and my pellet of choice is by far the RWS superdome. I read a post earlier saying the RWS point, and I would tend to agree with that too. The RWS weights seem to work well in the Cf-x.

Also, in response to the backstop question, I have had great success with a homemade backstop, especially when looking for a big one. I found the biggest cardboard box in my house (a widescreen tv box would be perfect), make sure it is at least a foot deep (in the direction of the moving pellets) and fill it to the brim with all your old newspapers, phone books, magazines, etc. THese wil stop a pellet quickly, but more importantly disperse the pellet so that there is less of a problem when hitting the same spot over and over. And if worried, just put some more newspapers in there. It also catches the bits of fired pellets, keeping lead out of your yard!


All in all, I love my CF-x, it is tough, powerful, and is more accurate than my shooting can produce yet which is more than I could ask for at under $200

Dave (the other cf-x guy)

At January 05, 2007 5:22 PM, Anonymous Dave said...

Some other odds and ends concerning the cf-x:

1. I have found that rubber sealing foam (i had some left over from a boat construction) works extreemly well as a pellet holder. It is about an inch wide and can be cut into any length desired. I cut mine about 4in long. Then take a drill bit about the size of a pellet (not in the drill) and press/turn the bit into the foam rubber. Dont go all the way through though. I fit to rows on mine and it functions just like the holders sold at pyramid.

2. ALso, for all synthetic stock owners, I have found that elmer's rubber cement works excellently for attaching things semi-permenantly to the stock of your rifle. I used it to attach my pellet holder to the butt of my cf-x (as constructed above). It holds things on the stock for as long as needed, but then you can just pull, and the thing will come off. THen some rubbing with the palm of your hand will take off all the cement that was on it, leaving your stock as it was before.

3. I was able to connstruct a bipod for my cf-x as well. Using 2 plastic pices that i stumbled on by accident. THey can be found under the pumps on new handsoap containers (the plastic piece is what holds it down) ask your wives/mothers if they know what i am talking about, I bet they will. Anyway, I took two of those and embedded them in a piece of wood to which i then attached two pvc pipes at the proper angles. On the bottom of these i insterted wooden plugs (made on a lathe) and then dipped the feet in the do it youself rubber coating stuff. It doesnt look pretty, but it works well. The plastic pieces, with a little push, clip right onto the underlever of the cf-x, and can just as quickly be removed for cocking. It isn't rock solid, but certinly is better than resting it on air.

4. I have attached a BSA air rifle scope that I got when i got my gun (from cabela's) IT is the BSA 2-7 x 32 mm It was suggested that long scope dont fit well, but this is a large scope and it works quite well for me. I hav eit positioned as far back as possible, but only because it works for my sighting. It may not work for everyone, but I think its great. Especially with the adjustable focus/paralax and the adjustable magnification seem enough but not overkill.

5. WHen hunting at night (for anyone that does ---especially RATS!!) I have found that it is possible to remove the from sight (non permenant and non breaking) from the gun. just push out the tension pin and unhook the underlever to slide off the barrel shroud. The post can then be slid out. After reassembling it w/o the front post, there is a small hole, but also a groove. I attached a small pressure switch torch (flashlight) to the front by sliding the torch's clip into the hole. It fits perfectly (my torch is the Gerber infinity ultra task light) and illuminates everything out to about 15 yds. Worked well for night hunting and could probably be used for other things (this techneque got me 2 rats!!)

***note: gamo/pyramid air/BB peletier/ me do not endorse/guarantee/recommend any of these modifications without serious thought to any dangers or consequenses and we accept no responibility for anything resulting from their use/implication***

Hi B.B.
I was shooting my cfx one day and accidentally shot with the breech block in the open position (I was kinda frustrated with my groups and got distracted by my dad but still mad at myself forgetting that after 1000 shots). I could hear the compression in the cylinder kinda built up with this sorta "pooof" sound. I was afraid the cylinder and seals would be gone and make the gun unshootable but it actually seems to work okay. It sounds the same and seems to shoot with the same velocity (from what I can tell, I dont have a chronograph). The only thing I can tell, which is preety faint, is that when I push the underlever back up I can tell it isn't as smooth (its easy to move and then a little harder and then back to easy)... I'm pretty sure the compression pushed out the cylinder a little but I think all the seals are ok as of now. Im just wondering if this really hurt the gun and if it did how much velocity will i lose from this. Will the gun break after another 500 pellets, ECT. I'm just looking for what everyone thinks on the situation.

At February 15, 2007 3:45 PM, Blogger B.B. Pelletier said...


You didn't hurt your gun. All you did was retard the piston by not allowing the compressed air to escape. You also proved that the breech is sealed well.

Keep on shooting.

I am trying to get one brought out to South Africa by someone traveling from the States next month. I will let you know how it goes.

This seems like a stupid questing although you say there is no such thing. On the CFX’s current trigger the first stage can be adjusted. How far can you turn the adjustment screw? If I keep on turning it clockwise to shorten the first stage will it eventually come to a stop at its maximum adjustment or will it fall apart?

Are you trying to remove all the first stage travel? I'm not sure that's possible.

Hi Trevor

I went with variable powered Gamo scope which I bought from Nicholas Yale in Braamfontein. I basically only had a fixed focus Gamo or variable focus Gamo to choose from. I am not sure that we have all that much of a choice in SA when it comes to scopes for air rifles, but one I got has made a huge difference to my shooting.


At March 28, 2007 2:10 AM, Anonymous Trevor said...


You are right about the scope choice. There shouldn't be a problem importing one from this site? We also have a problem with pellet choice. Can one get Crosman Premier, Accupell ect here? What pellets are you using? Rosenthal SA ( Cape Town, Hout Str.)imports the Weihrauch and I am in a quandry as to which gun to buy. B.B. mentioned that the HW 97 and CFX are sensitive as to the hold, and I have had a sensitive airgun before so this puts me off. A sensitive airgun is a complete pain. I need an inherently accurate airgun, not too high powered so I'm looking at the HW57 (820ft/s) with the BSA 3-12 - 44. B.B. has not done a test so I'm buying a bit blind. A lot of people mention the creepy gamo trigger so that also put me off the CFX. Actually, is it such a big problem?

Hi Trevor

I haven’t been able to find Crossman Premiers so I have been using Crossman Premier Hollow Points which I got from www.bulldog.co.za. They are fairly accurate as I managed to hit a mynah at 30m the other day, but it may have been a fluke. I have also been using something called a Predator with straighter sides which I got from Sharpshooter in Sandton City which seem to give a tighter group. I have got a couple of others, but these seem to be the best for the CFX.

I unfortunately don’t know the Weihrauch range at all. All I’ve got is the CFX and an old BSA Meteor. The Gamo trigger isn’t great, but you do start getting used to it when you shoot a lot. However, I have gone ahead and purchased a new trigger from www.charliedatuna.com which I should hopefully be getting this weekend as switching back to the Meteor every now and then highlights the failings of the Gamo trigger.

Hi, i read somewhere that airguns/air rifles require scope that can handle both forward/backward shock, is this true? i understand that any spring airgun has more forward shock (forcing the scope backward) than backward shock, mostly bc of the spring direction. rebuttles? thnx

Pellet choice: depends on purpose and range
In general:

Pellet speed depends on ballistic coefficient (air drag) and how tightly they fit in the barrel to harness all the compressed air. eg, wadcutters trap air better than pointed noze pellets.

light pellets travel fast but lose stability downrange, 25 yd+

heavy pellets travel slower and have more inflight stability

Punch or penetration depends on speed when it reaches the target and head shape.

For the gamo 1000 fps airgun series:
they tend to like medium-weight pellets: ie Gamo Hunter, RWS Superdome, Beeman FTS or Trophy.

Heavy pellets cant gain enough kinetic energy from this powerplant class and the bore length. ie, Beeman Kodiak. They exit with muzzle velo around 950fps +/- 7fps. Test done with laser lines, Gamo Shadow 1000.

Light pellets, in general, exit with 970-980fps (depending on head type). the Gamo PBA pellets brag supersonic speed, but this is only for 10-13 yd, the downside is the sonic boom (more like crack) jolts the pellet and sends it tumbling downrange, NOT good for accuracy. but it's great for hunting medium game shortrange, less than 25 yards. see the gamo PBA pellet demo, it can take down a bore!

then there's pellet head type: read here:http://www.beeman.com/pellets.htm

Scope question,

Yes apring piston guns do recoil in both directions. The forward direction is the hadrest one. The scope goes backward because the airgun goes forward.

Scope makers have caught on to this and most scopes are breaced for it.

At April 09, 2007 10:34 PM, Anonymous Anonymous said...

so would a leapers 3-9x32 handle this forward shock? lots of scopes dont say regarding this must-have feature.

At April 11, 2007 9:00 PM, Anonymous Anonymous said...

The 3-9x32 scope has the "TS" symbol on the page so it will hold up to the cfx. I think tom gaylord tested some leapers "TS" scopes (TS=True Strength) on a webley patriot which is basically the hardest recoiling air rifle out there and they all held up to the punishment. These TS scopes are tested hard by leapers in this test http://www.leapers.com/pages/optics/Recoil-Resistance-Tests.swf.
I think Tom Gaylord said the hammers in the test weighed like 11 lbs or something and were dropped from a meter up, and the scope was vibrated for 15 mins. The 3-9X32 will hold up to the cfx's recoil.

Was wondering if you could shed some light onto something for me. I don't have a chronograph, so I'm comparing my Shadow 1000 to my CF-X by means of relative tests...

When I fire identical pellets (CPLs, RWS Superdomes, etc.) into a 2' x 4' x 3/4" sheet of plywood (at distances of 10 ft and 20 yards), the pellets fired from the Shadow are much louder on impact than those fired by the CF-X (a loud "smack" versus a dull "thud" of sorts).

This lead me to believe that the Shadow was shooting them faster, but I then took a phonebook (~800 pages thick) and fired a shot from the Shadow and a shot from the CF-X into opposite corners of the phonebook and examined the depth of any visible page "trauma". At 10 ft., the shot fired by the CF-X had caused visible damage 150 pages deeper than the Shadow's shot. At 20 yards, the CF-X's damage was about 60 or 70 pages deeper.

My question being... any idea why the impact into the plywood sounds considerably louder with the Shadow? I don't want to spend $100 on a chrono just to set my mind at ease about the performance of my brand new CF-X!

Any insight is appreciated!

Hey, am considering ordering a cfx for myself over the web, and am unable to actually physically hold one and inspect it.

What I want to know is how does the rotating breech work, i mean when the breech is closed, what fills up the large groove? surely this cant remain hollow space, it will surely waste some of the power.

I cant find any other good close-up pictures of the rotating breech on the internet. Just cant seem to get my head around this issue.

Words of wisdom appreciated, and thanks for this awesome review & blog,


At May 20, 2007 1:08 PM, Blogger B.B. Pelletier said...


The loading groove is cut on an excentric axis to the bore. It doesn't align until rotated into the open position. When it's closed there is a solid wall that prevents the air from passing through, and the air transfer port, which is also cut on an excentric, aligtns with the bore.

Don't worry - it works.

I finally pulled the triger on that CF-X.

I am just wondering if you guys could find a holding technique for good accuracy.

I have a sandbag and I can get myself a gel bag, but is there a way to simulate the resting by holding the rifle in the hand?

Have you tried holding the gel bag in your hand and resting the rifle on it?

Thanks a lot.

At May 30, 2007 1:08 PM, Blogger B.B. Pelletier said...


Use a light hold and don't grasp the stock. Let the rifle move in recoil and hold on target long after the shot has gone off.

Hey BB

I've commented a couple of times about lubricating my cfx's chamber. You said to put a drop of chamber oil
(Crosman RMOIL?) into the transfer port. Where is the transfer port on the CFX? Or should I just put a drop down the barrel?

Thanks, Kyle.

Drop three drops of chamber oil down the muzzle and stand the rifle on its butt for at least an hour.

Do this every 3,000 shots or so.

At June 02, 2007 9:22 AM, Blogger B.B. Pelletier said...

.22s are generally slightly louder than .177s because of their greater air flow. The difference is like the difference in sizes of sparrows.

Do you have in mind any bipods that can work on the CFX? There are 3 in PyramydAir, does any one work with the CFX?

I don't have a CF-X to try a Dragon Claw bipod on. That's the only good bipod I know that might work, but I'm concerned that the clamp won't allw the underlever to close.

So call Pyramyd Air and speak to Gabe. He should be able to check the fit for you.

Is there any chance that the plate on which the scope rings mount actually moves its possition from the rifle?

The grooves are not "molded" into the body of the CFX - like they are on the TX200. There is a "mounting plate" on top of the rifle which is bolted in place.

I know that this "mounting plate" is common in many air rifles. Does that thing move at all after some time? How do I stop it?

Thanks for your time. You are making everyone a better air gunner. Especially young ones like me who are barely over the legal age limit! :)

At June 09, 2007 8:11 AM, Blogger B.B. Pelletier said...


That plate is the recoil stop for the rifle. No, it should never move. The force against it is perpendicular to the screw holding it in place. It is a good. solid stop.

I have some questions on it though.

In the following pictures, there's a hole and a screw. Which one of the two is for the stop block? One is wider than the other... Can you please explain their use?



Note that the rifle came like that, there was no Gamo stop block on it or anything.

Thanks a lot

At June 12, 2007 7:51 AM, Blogger B.B. Pelletier said...


You don't need a stop block if the base has a hole for a vertical pin. The hole to use is the smaller one. The larger one is just a screw access hole. If the stop pin of your mount is too fat for the smaller hole, grind or file it to fit.


At June 14, 2007 10:54 AM, Blogger andreas said...


Thanks for the info. Now that I think of it, I believe that the screw must be the vertical stop for the mounting plate itself on the rifle.

Tom Gaylord seemed to fit the B-square stop pin in the small hole. I don't think I ll have a problem fitting it since I ll be getting B-square mounting rings too.

I put accushot high rings on my cfx which have a stop pin in the rear ring. The pin for this ring fit. Just thought I'd let you know. BTW, it seems on the gamo website that the cfx is supposed to come with the gun, I noticed that you said that yours didn't come with one, neither did mine, I wonder whats up with that.

Sorry I mean the gamo stop block is supposed to come with the gun.


At June 20, 2007 4:51 PM, Blogger andreas said...


Yeah, I know... strange isn't it!? Maybe it has something to do with models reaching the US or the EU. I live in the EU and I got no stop block. I heard they are not so good though, and they are only worth $10 so I didn't make any fuss about that when I bought the CFX.

I have one question on the CFX's dovetail rail:

It seems that there is a dovetail rail on the rifle, but there is another dovetail rail - a more angular one mounted-bolted on top of it?

What's the deal with that? Should I just mount the rings on the "angular top rail" or should I remove that and mount the rings on the rounded rail which is "molded" in the rifle?

You can use the pictures I posted a few posts earlier to see what I am talking about. I think you can tell from those...

At June 21, 2007 9:02 AM, Anonymous Anonymous said...


Yeah I now see what your talking about with the two dovetails. I'm certainly no expert but I believe the round tube is the spring tube which encloses the spring, and cocking parts. It seems that a dovetail shape was cut into this to mount another dovetail onto it. The only reason I can think of for this is to place the scope mounting surface high enough so that when a scope is mounted you can have a hole to put your solid locking device into. If you took off the "upper" dovetail I don't think there would be any holes for you to put the stop pin in because the spring would be sliding underneath and would catch the stop pin of your mount when you fired the gun which would be bad. But then you see that big screw in the upper dovetail which I imagine anchors the upper dovetail to the spring tube/reciever and wonder how thick the walls of the springtube are for that large screw to be threaded into. Long story short I mounted my leapers 3-9X50 which is a pretty large scope on the upper dovetail and I haven't had any problems with it moving. Maybe if yor brave you could try taking off the upper dovetail (you only need to take out 3 allen screws) and see whats under it. But I don't see any advantage to the lower dovetail because that means for a bigger scope you need even higher rings as compared to mounting it to the upper dovetail. Hopefully BB or someone with more knowledge could intervene and answer your question or correct any of my wrong assumptions, but thats what I think.

Hope it helps, Kyle.

At June 21, 2007 12:42 PM, Blogger andreas said...

Kyle, I don't think it's there to allow space for the stop pin.

Rifles like the TX 200 have no problem with space: http://www.pyramydair.com/articles/scopes-part2/

As you can see the pin goes in OK.

I really don't have any problem with the extra rail, but it's weird.

I am getting a leapers 4-16x50 by the way...


At June 21, 2007 2:37 PM, Anonymous Anonymous said...


Good point about the tx200. Maybe I will take that rail off just to look. Maybe the spring is farther forward in the reciever than I thought they were. Like I've said I'm still a novice, but hey if you can mount to the lower dovetail you'll have a unique cfx because I have never seen one with the top rail off. But theres no problem with the top one either so I guess its up to you.


At June 22, 2007 2:46 AM, Blogger andreas said...


Let us know if you take it off. I can't see why they put it there in the first place.

Hopefully BB will post here before any of us try anything we shouldn't, and tell us the reason that rail is on there.

I just received an email back about the difference between the two 4-16X50 scopes. Apparently the cheaper one is older version and does not come with the lockable turret, while the newer and more expensive scope does come with the lockable turrets. It came with my 3-9X50 and its a nice feature. Heres what Sharon said in her email to me.

Dear Customer,
Thank you for contacting us. The first scope is the older version of the 2nd scope, which is an upgraded version. The second one offers a zero locking resetting knobs. This is an unbelievable feature. Basically, you can focus your scope in at a setting, and put the gun down with the scope and it stays sighted in. In addition, lets say you sight in your scope at 25 yds. with lets say a 15.8 grain pellet, then resight your scope in for a 12.4 grain pellet at 30 yds you can click forward 3 times and back twice, etc to get back to where your scope was sighted in. I know this sounds confusing, it is hard to explain via email. I apologize for the confusion. If you need further explanation on this or would like to place an order, please call me directly at 888-262-4867 ext 228.
Thank you,
Sharon CSR

Hey all,

Just wondering if anyone had any better luck with bipods than what I provided above (the PVC and soap plastic clips). I don't think any of the new air rifle specific bipods will work unless they rise less than about 1/16th of an inch above the tube they attach to, otherwise the underlever will not close. I am interested in using the two small gaps between the stock and the mechanism of the gun which are located just in front of the mainspring housing (ie where the mainspring tube meets the barrel) to mount two separate bipod arms, one on each side obviously. That way there would be no interferance with the underlever.

I'm attempting to construct one like I described and it is more difficult than I had thought, especially because I want to avoid doing anything permanent to my stock Any comments are welcome.


At June 29, 2007 8:38 AM, Anonymous Anonymous said...

Hey Dave,

I was thinking of somehow trying to mount a bi pod to the cocking linkages of my cfx. If you pull the underlever towards you, you will see that small rectangular flat piece of metal near the stock on the underside of the gun. Its hard to explain where it is but I think you know what im talking about. Anyways I was thinking of somehow taking that piece out, drilling a few holes in it and and the attaching a block of wood to that. Then you could clamp a clamp on bi pod to that. I don't know if there's enough room for the bi pod without having it in front of me. But its some thoughts.

I just bought a Gamo .177 cfx that cvame with a Gamo scope and Raptor gold pellets. I also bought a can of Premier Crosman 'hollow points'. I attached the Gamo scope and set up a paper target at a distance of 40 walking steps. Approx. 33 meters? I shot 4 very slow and carefull shots with my gun resting on a rolled up tarp on the hood of my truck using the Premier hollow points. I was astounded! The 4 shot group would fit on my little finger nail with 3 of the pellet hols touching! HOWEVER, my happy astonisment didn't last long once I tried to adjust the scope for bulls eyes. Now my shots are hitting about a 1 1/2" to 2" group. I bought the gun to kill chipmunks that are messing with my property. I'm lucky if I can hit one chipmunk out of every dozen shots at 40 steps. I'm not very happy about this. What can I do to get good groups?

At June 29, 2007 12:25 PM, Blogger B.B. Pelletier said...

Rest the gun on the flat of your open palm, just in front of the triggerguard. It should feel very muzzle-heavy. Do not touch the side of the stock with your fingertips. Hold the rest of the rifle as lightly as you can, so the gun can move as much as it wants to when it fires.

Continue to hold on target for one full second after the gun fires.

And don't use those horrid Raptor pellets! The Crosman hollowpoints should be very good.


At June 29, 2007 11:30 PM, Blogger Kayak said...

Chipmunk slayer,

if I were you, I would get some RWS superdome pellets. THey're what I use for everything. Relatively inexpensive (8.50? for 500) and they are a great match for the cf-x. I use them for hunting even with some success: multiple rats, a groundhog( yes BB I was able to get it with my .177), as well as some pidgeons. I would definitely get rid of those supersonic raptor things before you get frustrated with the bad results.

Congratulations on joing the cf-x club! I'm sure you will be happy with it.


At June 30, 2007 8:05 PM, Anonymous Anonymous said...

To B.B. and Kayak, I just got back from trying to shoot the cfx better. I tightened the scope mounts better and tried the open palm shooting style. I believe that is a better way to shoot, but i'm still frustrated and am thinking this gun was a mistake to buy.
Maybe it is the scope causing the trouble. The shots were high and right. So I adjusted for lower and left. Still hitting high and right. More low and left adjustment. Still hitting high and right. More adjusting low/left and the gun seems on pretty good. Then shots start hitting all over the paper again.
Under controlled and calm conditions using a steady rest for the gun, I'm as good a shot as the next guy pretty much. I should be hitting bulls eyes and right around it. (I'm a Viet Nam vet and I tied another shooter for first place in our battalion qualifying with the M16 back in 1969) I'm no Spring chicken but my eyesight is still good. I practice propper breathing technique while slowly sweezing off a shot and keeping the crosshairs on the bull.
I'll try RWS Super Dome pellets next. I really want to believe in this Gamo cfx .177. I'll keep trying. "Whatever it takes". If that means another scope or a custom trigger installation. Ed

At July 01, 2007 8:40 AM, Blogger B.B. Pelletier said...


I can read your problem through your words! You are trying too hard! And that is what is causing the inaccuracy.

The next time you shoot, align your sights then close your eyes. Take a deep breath and try to totally relax your body. When you open your eyes, your sights will be pointed at where the pellet is going.

To solve the problem, take that deep breath BEFORE you aim. Let half of it out as you align the sights and relax at the same time.

At first the gun will try to pull itself off target, which is what it is doing right now. Soon, though, you will develop the correct shooting technique and you will be able to keep the sights on target while relaxed.

Squeeze off the shot so you have no idea of when it will release.

Do this five times in a row and I bet you will see a dramatic improvement. I will blog this answer in much greater detail this coming week.


At July 01, 2007 8:53 AM, Blogger Kayak said...

Just as a side note to what BB is saying, just relax with it. I shoot my cf-x with horrible form (I'll be honest) I rest it directly on the wooden railing to my deck most of the time, and I am still able to his a dime out to about 25 yards. I think you should definitely try a bunch of different pellets. I like the RWS Superdome, but you might find one that works better for you so don't just take my word for it. And one more thing: double check that your new scope adjusts the way you think it does. I dont mean to belittle you by any means so please dont take it that way, I've done it a million times, but double check that the adjustment knobs change the projectivle strike location, and not the corsshairs. (IE. they are opposite directions) That may account for your continued inability to zero.

All in all, dont worry, we'll work this out. The cf-x really is a great gun once you get it going straight.

Good luck!

Truth is, I don't know what you mean by the above info. I hope my scope is on my gun the right way. The scope has a pin sticking down and I put that pin in a hole on top of the guns scope mount. I then tightened all the screws with the included wrenches.

B.B., My breathing and trigger pull is as you described. Maybe I'll have time to shoot at the range tomorrow and see how it goes.


At July 02, 2007 8:58 AM, Blogger Kayak said...

Sorry to be vague. I mean the recticle adjustment knobs. Normally, they have a direction indicator on them (an arrow pointing clockwise or counterclockwise and a direction, up for example). What I was suggesting is that that direction could indicate the direction that the projectile impact site moves on the target when you spin it that way, or it could indicate the direction that the lines inside the scope move. These directions are opposite so when your pellet kept hitting high right, and you adjusted low and left, you may have been moving the lines (crosshairs) on your scope low and left, which would just cause the pellets to hit further high and right.

I hope I was able to clear that up.


At July 02, 2007 12:01 PM, Anonymous Anonymous said...

Dave, Now I getcha. What I was getting at was that after about 3 or 4 tries at low/left adjustment, the shots fially hit around the black and a few in the black. The Gamo seems to be a very simple and basic scope. Not bells or whistles. I seem to have the scope sighted in as I have finally put a few pellets through the black. But some of the shots go really wild to. It's wierd. I'm new to pellet guns and have been reading various internet sights about springers. I've only put maybe 200 some shots out the barrel so maybe I have a way to go before the CFX mellows out. The barrel, the trigger, the spring chamber, etc etc. On the brite side, I just did a nice loose gripped shot that made a very clean kill on a chipmunk. The gray squirrel 2 feet away from the chippy barely took notice and just kept eating. The chippies are the only thing I shoot.
thanks B.B. and Dave PS: The next time I go by Gander Mountain I'll see what other pellets they sell. Not sure if they have RWS super domes but they do have various Premier by Crosman. ....or I'll order on line. This is fun.

Hey Dave,

I haven't had any luck with any of the crosman pellets. The premiers in the tin are a little more accurate compared to the cheaper crosman pellets. From what I've read on this site premiers from the cardboard box are better than the crosman premiers in the tin. I've also had good results from gamo match pellets. I can shoot one hole groups about 3/8" in diameter at 20 yards, I'm sure with some trigger time you can do the same. Just thought I would share my experiences.

Happy 4th, Kyle.

The accuracy problems were with Ed, not myself. You would have realized this had you read the previous comments. I am quite happy with my "trigger time" (I bought the gun just after it came out), pellet choice, and accuracy, which exceeds your own.

The shadow 1000 is more durable than the cfx? i really appreciate if you guys answer to my questions.

I haven't heard that one! So the spring is supposed to break?

Would a Shadow spring be any better?

They say that a gamo mainspring break at about 2000 rounds in cfx i just want to know if you guys just experienced that on your gamos, is that true?
thanks BB for the quick reply.

My cfx is at about 2800 rounds and the mainspring is fine.

Hi, I am new to air rifles and would like to know whether the Gamo CFX is accurate enough for target shootind and if it is fairly consistant.

To Kyle:

Thanks a lot for all your trouble! Now I can finally order! Thanks a lot, I appreciate it a lot.

Thanks for those B-square Adjustable articles too!

As long as you are referring to informal target shooting, the CF-X will be fine. It's no Olympic 10-meter gun, but neither are any of the other spring piston pellet guns.

It is very consistent.

I'm looking to buy a new air rifle that's accurate and powerful for target shooting and pest control. Is the Gamo CFX a good choice? Are the sights good or is a scope recomended. I'm mainly looking for a gun that's good to practice my accuracy with. Any input is much appreciated.

The CF-X is a wonderful gun. I recommend that you start with open sights and then go to a scope later. That way, you'll be familiar with the rifle when the scope gets installed.

thanks b.b.

Have you used the scope in the CF-X combo kit? If so is it a sufficient scope or do you recomend buying a different one? Also, I've been reading various articles and sounds like crosman premier light pellets are the best. Would you agree or are there better ones to use with the CF-X?


At July 18, 2007 5:32 PM, Blogger B.B. Pelletier said...


No, I haven't tried the kit but I assume the scope will be okay. I would suggest the 2-7 scope, if possible.

The Leapers that I used is probably better, but why not try the combo first? It will work.

I didn't have the gun a long time so Premier lites were the best pellet I saw. You might read what others are using though, because if I recall correctly, some like the Gamo and RWS domed pellets, as well.

I would like to know youropinion towards the gamo vipermax and the gamo cfx. which is better for accuracy and which is better quality?


At July 22, 2007 9:45 AM, Blogger B.B. Pelletier said...

Well, both guns are made by Gamo, so the quality is going to be the same.

I like the CF-X a lot as an inexpensive spring piston rifle that is easier to shoot than a breakbarrel. However, my recent testing of the RWS Diana 34 Panther shows me a breakbarrel can be even more accurate.

As for the ViperMax, that's an airgun offered in the UK. It appears to be the same as the Viper, which is sold in the U.S. Of course the power is limited to the UK legal limit of 12 foot-pounds. It should be a very nice air rifle. I would still opt for the CF-X, however.

Thanks B.B. Pellitier,
What is the big fuss over sinthetic stocks? Is there any big difference between sinthetic and wooden stock?


At July 24, 2007 2:08 PM, Blogger B.B. Pelletier said...

Synthetic stocks don't warp and swell in the presence of moisture. They are more stable and therefore tend to be more accurate - or perhaps less of an influence on the accuracy of the gunm.

Recently, my friend and I both purchased Gamo rifles. I had been impressed with my friend's Shadow1000, and i was tired of pumping my old bb gun, so I got a Gamo Big Cat, my friend, for whatever reason, decided to buy the CFX. The other day, we were shooting, and he found it hilarious that the Big Cat did not have any open sights, and frequently commented on it. After we had been shooting for a bit, he noticed that his shots were starting to miss by quite a lot at about 50 feet. After some inspection of his sights, he noticed that the bit of plastic on the muzzle of the CFX had become loose and was turning, causing him to miss all of his shots. He tried tightening the screw at on the plastic bit, but it was still loose. Is this a problem you have encountered before, or is it just karma? Also, how would you recommend fixing this?


At July 26, 2007 6:28 AM, Blogger B.B. Pelletier said...

I'm sure that plastic piece is bonded on, so it will have to be reglued. If your friend doesn't want to do the job, Gamo USA should be willing to do it.

Do spring rifles ever loose accuracy after their springs getting weak? If they do can you replace the spring?


At July 26, 2007 11:32 AM, Blogger B.B. Pelletier said...

Accuracy doesn't change. They just lose power. Yes, the springs can be replaced. I did a 13-part blog on that very process:

I have posted before and am a new cfx shooter/first pellet gun ever. I haven't been able to really get down to business shooting this .177 but I will shortly as I have joined a range. I will post in the future about my experience at the range where I don't have to put up with some 'girly man' driving buy telling me I shouldn't be shooting out here in the woods on a gas line where I have safely set up saftey considerations. The last thing I need to do is hurt someone. Safety is job #1.
