The Benjamin Discovery – Part 2 Accuracy

by Tom Gaylord

Part 1

Initial testing
I received two prototypes of the Benjamin Discovery for testing in July 2007…one in .177 and the other in .22. When you finally have a prototype rifle to test, every project gets scary, because you don’t know what the gun is going to do. If these rifles shot groups the size of Oreo cookies at 25 yards, we would be in trouble. But they didn’t!

I could test only the .177 at that time because the .22 had a fast leak at the manometer. I fixed it the same day after the shooting was over, so the first test was with the .177 only. The first test was in the backyard at 21 yards and the groups…well, just look at them.

 

Not bad groups for 21 yards. We’re off to a good start.
 

Look at that group of JSBs in the center. Still 21 yards with the .177.
Not a lot of time was spent at this close range, because I could see the gun was going to shoot. And, if the .177 shot well, the .22 probably would, as well, so I shifted focus to sealing the leak on the .22 and getting them both ready to take to my rifle range.

At the range
The club I belong to has 25-yard, 50-yard and 100/200-yard ranges. I started on the 25-yard range, just to give the .22 a chance to show its stuff. The scope I used was a Leapers 8-32×56, because I knew this rifle was going to appeal to long-range shooters and those who want to get into field target. Yes, to answer one question, the .177 Discovery will be fine for starting out in field target. To answer another, the two-stage trigger breaks at 3 lbs., 12 ozs., which many will say is heavy, but I think it’s right for a sporter. It’s non-adjustable and not much can be done to lighten it, but a shooter who can’t shoot a trigger of this weight needs to practice!

25 yards
The groups at 25 yards were okay, and one .177 group of JSBs was astonishing. It measured 0.234″ for five 10.2-grain JSB Exacts. The average group of .177s was more in the 0.375″ range. In .22, the smallest group was also shot with JSB 15.8-grain Exacts and measured 0.354″. On average, .22 groups would enlarge to 0.60″, so I was ready for one-inch groups at 50 yards. They happened, but were the exception.

 

At 25 yards, the .22 caliber rifle proved it could shoot, too.
 

This one group of .177 JSBs at 25 yards was quite astounding, measuring 0.234″.
Then 50 yards
The average group size at 50 yards in both .177 and .22 hovered between 0.75″ and 1.0″, though there were several groups under a half-inch. The best group of the session was a .22 caliber group of JSBs that measured 0.374″. For some reason, Crosman 10.5-grain Premiers took over from JSBs and produced the best .177 groups…0.458″.

 

Best .177 group of 10.5-grain Crosman Premiers at 50 yards measures 0.458″.
 

This is the best 50-yard group of the session. Five 15.8-grain JSBs in a 0.374″ cluster.
Under ideal conditions, the Discovery is fully capable of half-inch groups at 50 yards. Now and again, it does better. But a puff of wind or a pellet that doesn’t weigh the same as the others and the groups open up. This is way better than I would have guessed, especially since I was transferring the scope and mounts between the two rifles on the two different ranges.

Yes, you can shoot field target with it, and, yes, it’ll make a wonderful hunter. I’ve told you where the trigger breaks and some will break even heavier. But, it’s crisp and positive, without creep. The scope rail is 9″ long to accept the largest astronomical observatory telescope your money can buy. And speaking of money, the Discovery left some in your pocket, didn’t it?

It looks like Pyramyd Air sells the kit for a little less than Crosman; so when they list the gun by itself, we might see some savings there, too.

88 thoughts on “The Benjamin Discovery – Part 2 Accuracy

  1. Now that my initial excitement over this new gun has died down, I think I’ll just stick to my old Sheridan and Benny pumper. My kind of shooting, running rabbits or an occasional squirrel, requires a light weight, quick handling rifle with enough power for the job. A .20 or .22. .177′s just don’t cut it. I’d buy a Sheridan or Benny in .25 if they would get in gear and make one.


  2. After avoiding weighing pellets for a long time, I have become a believer. It is partly that one has to be a very good shot to see most of the effects of pellet weight variance (and it is a pain in the neck — literally — to weigh them). I used a digital scale that can resolve to .01grains and sort into .05grain groups. I shoot from any one group — I don’t care what the actual weight really is — I just want them all to weight about the same.

    Results are significantly better with this approach. You get rid of any “bad” pellets in the inspection process and I do find a variation of about .3gr which can certainly affect 55yd shooting.

    Again, this is for the marksman, not the plinker. Waste your time learning to shoot well before weighing.


  3. bb,
    You say “two-stage trigger” without elaborating. I was not aware that Crosman made a two-stage trigger, at least for the 22xx series trigger group, which is what the Discovery has.

  4. Hello BB and everyone,

    Got a question, which I believe I should know the answer for, but not really sure after looking at some schematics, and associated products.

    When using a 12g CO2 powerlet in the 22xx series guns,…
    – When the powerlet is pierced, does the pressue of the gas open the spring loaded valve?
    -…or as the powerlet gets pierced, does it move forward and “help” push the valve open?

    I guess this question could also be asked about the 88g Air Source cylinders, when used for the 850 AirMagnum, and Crosman AirSource Adapter for the 1077.

    I have an old and a new AirSource adapter for my 1077. At the cylinder connection point, the old one looks like it just pierces. The newer one has been redesigned and has a disk in front of the piercer, and the piercer looks like it has a hole in it for the gas to pass thru. It looks like the disk will be forced back, to allow for piercing, and maybe is pushing open a valve.

    Any insight would be appreciated. Even if that insight is for me to just call Crosman…lol.

    Thanks



  5. Don,

    I didn’t think a two-stage trigger required elaboration. There is a first or take-up stage and a second or release stage. All two-stage triggers work the same way, though some of the ones found on target guns allow loading some of the trigger-pull weight into the first stage.

    Beyond that, what haven’t I said?

    B.B.


  6. SquirrelKiller,

    The powerlet or AirSource cartridge doesn’t move when pierced. The gas flows through the hole made by the piercing pin, through a port and into the firing valve, where the pressure of the gas helps the valve return spring CLOSE the valve. You can even hear this happening most of the time.

    The gas circuit is open all the time from the powerlet to the firing valve.

    Another great report!
    What 30mm rings did you pick?I was looking at the Leapers 3-12×44 swat mini but theres not many 30mm rings.I cant wait to see the fps+flb on the discovery 22.cal..I was going to buy another springer but this rifle changes everything!Also does your discovery feel right with such a large scope on it?Top heavy I meen.


  8. bb,
    Re: the two-stage trigger, I guess my understanding of what this term means was slanted to the target trigger, as you describe. I didn’t realize that take-up was also considered to constitute a first of two stages. I certainly didn’t intend to sound critical.
    Thanks for the reviews. Keep up the good work.
    Don



  9. Don,

    I wasn’t snapping at you. I just didn’t know what else to say.

    Yes, the first stage of a two-stage trigger is what some people call the take-up. On military rifles the take-up has some resistance because the military demands a heavy trigger return spring. But the second stage is where the real trigger pull weight is.

    Only a target trigger allows you to load some of the actual pull weight into stage one, while subtracting it from stage two.

    B.B.


  10. b.b.
    So you can use a 38″ dovetail on a 11mm rail?Also in short what do you think of the leapers swat mini on a discovery?Theres no reviews on this scope.I like the mini just to keep the wieght down.Mine will be for hunting.


  11. B.B.

    Fascinated with the accuracy tests as always. This sounds like some gun.

    I hate to be boring, and I know you had a post some time ago to the effect that just about any oil was okay for the mainspring of a spring rifle. But I was wondering if you could tell me if pellgunoil and/or ballistol are okay for the mainspring of the IZH 61. It’s been making a harsh metal-grinding sound that’s frightening me a bit and sounds like it could use some attention. Thanks, as always.

    Matt61



  12. B.B.

    You might recall the video some time ago of the guy with the S410 sidelever breaking bottles at 218 yards. One of the YouTube comments claimed that a pellet wouldn’t have the energy to break a bottle at that distance.

    This sounds like a claim that can be calculated so I ran it by a relation who is a professional physicist. The complications having to do with air drag are way, way over my head. He came back saying that he couldn’t see how an average pellet below the speed of sound could have a range over 100 meters. That can’t be right either since there plenty of anecdotes on this blog about people shooting accurately at over that distance.

    I think the missing factor must be the spin of the pellet since I know qualitatively that spinning the projectile increases range. Anyway, the question is if you could give me an estimate of the twist rate for the S410 or some reasonable number for an air rifle. The S410 site just mentions a 12 grooved barrel and I don’t think that is related. Thanks.

    Matt61




  13. Benjamin .25,

    That was someone’s wishful thinking. No one I know of has done such a conversion.

    But why do you want one when the power curve of the rifle is so perfectly suited to .22 pellets in the 15-grain weight range? A .25 running 30-grain pellets would be a lead sled in an existing multi-pump.

    Perhaps what you really want is a purpose-built multi-pump that can generate 30 foot-pounds or more?

    B.B.


  14. B.B.,
    This gun is certainly sounding like a keeper. You mentioned in the first blog that the design-to velocity for the proto was 1000 for .177 and 900 for .22. Did I miss if you stated the actual velocities?
    Also, did you say if it has adjustable power.
    Thanks for pushing Crosman on this. A very major coup! Maybe .25 cal Premiers one day? LOL.

  15. Matt61 and everyone else,

    About a decade ago, some black powder cartridge gun writers went to an Army missile range where they had been invited to test the ranges of typical blackpowder buffalo rifles.

    The “eggheads” all claimed that a .50-caliber 650-grain blackpowder bullet from the .50/70 Government cartridge that left the muzzle at 1,200 f.p.s. could not go farther than about 1500 yards. According to the Army’s millimeter-wave radar, it went well over 3,000 yards. The .45/70 405 made 3,600 yards.

    Pellets travel about 500 yards, as far as anyone knows.

    B.B.


  16. Pestbgone,

    I have written so many articles about the Discovery that I get confused where I said what. I did put the velocity into my Shotgun News column, but that hasn’t hit the newsstands yet.

    Friday.

    B.B.


  17. Good Morning,

    The close release of the Super streak, and discovery so close together has given me a headache.

    Will you be doing accuracy and power tests with the Super Streak in .22? Will (and this is verry doubtful) either rifle be released in .20 cal that you know of?

    Having shot both the streak and the discovery, if you wanted something practical for hunting, which would you choose and why?

    All hype aside, I really want to get a new hunting airgun at a reasonable price from an American company (besides, I just like crosman anyway). Crosman seems to be taking airgun hunters quite seriously, but now my brain hurts.






  18. BB,

    I looked into attending the Las Vegas SHOT show since that is about as close as a show seems to come to California (one that includes airguns). However, the SHOT show web site states “Only members of the trade may attend the Show.” Why is that?

    .22 multi-shot


  19. .22 Multi-shot,

    SHOT Show is a trade show. The manufacturers and importers are there to sell to distributors and large chains. They are showing their new products to all the dealers who may or may not be able to place orders.

    Nothing is geared to retail at SHOT.

    But the NRA Annual Meetings is a similar show with the same manufacturers and importers that’s geared to the public. It travels around the U.S. This year it will be in Louisville, KY, which is pretty out of the way for you. In 2003 it was in Reno.

  20. jj,

    As I’ve told so many others already, you’ll have to wait until Friday.

    I’m not stretching this out to be mysterious or to pad the blog. But if I just make a core dump on the first day, the rest of the time I will be explaining what I meant by all the cryptic notes. So I’m taking my time to explain not just what the gun does today, but some of what it had to go through to get there.

    B.B.


  21. BB,

    The phrase that caught my attention was “The scope rail is 9″ long to accept the largest astronomical observatory telescope your money can buy”. Being curious, I looked back and realized you were using a 56mm objective with 8-32 power range. I realize hyperbole was your employed rhetorical device, but that scope is getting close…you should be able to see Galilean moons of Jupiter and rings of Saturn no problem; craters on the moon and Orion nebula should be easy as well. Maybe some of us can fund scopes under science or continuing education budget.


  22. BB,

    Works for me.

    [I hear the teacher in there .....]

    Friday it is.

    ps: Don’t forget the blog on the history of Crosman’s pellets.

    jj


  23. BG_Farmer,

    Do you know I have tried just that? I tried it with a 6.5-20X56 Leapers scope years ago. It didn’t work too well because of the shaking of my hands.

    Then I bought a Celestron Maksutov-Cassegrain 30-90X65 spotting scope. It isn’t really a Celestron – they get it made in China or Russia, but I can see house numbers 1/8 mile away and they are clear.

    The problem I have is the tripod. It has a 1/8″ camera attachment and I don’t know how to get it on a decent tripod with an equatorial mount.

    In other words, I can SEE stars – I just don’t know WHICH stars they are, because there’s no good way to guide this scope.

    Any suggestions?

    B.B.


  24. JJ,

    I’m about to travel for two weeks by RV to the SHOT Show. While I’m on the road I won’t have access to guns, targets or my other equipment, so I thought I’d take along several blog ideas that are easier from the road. This will be one of them.

    B.B.


  25. BB,

    Enjoy the show, regards to your lovely other half, bring back lots of goodies and ideas for those of us who can’t make the show, and safe trip.

    jj


  26. b.b
    I live in louisville ky.Where and what date is the NRA annual meeting?Will I actualy get a chance to see the discovery???

    As far as not knowing what stars are where.There is a computer program called Starry Night.IT SHOWS EVERYTHING!!!I have a 10″ DOB and this program realy helps.You can get it at oriontelescope.com.I’ve got starry night enthusiast but there are a few different versions.Its the best Ive ever used.I hope this helps.




  27. BB,
    Get yourself one of the old CG5 mounts. With a scope that size you can use the aluminum legs that come with it. Look for one with the 5 lb counter weight. They came with 5, 10 or 20 lbs which was very optimistic. Celestron used to sell them in a package with the 8 and 91/4 inch schmidt cassegrains and most people had to upgrade the legs or the whole mount. They have nice manual controls and can be upgraded with motors. You should be able to find a good used one for $150 and it will be very stable and even let you upgrade the scope size to 5 or 6 inches. They come with a dovetail plate that you can drill to mount to your scope then you can remove the plate and scope together to transport. They are Polaris knock offs.
    Dont get the new CG5, its too expensive and too heavy for your needs.

    Sam



  28. i wouldn’t say that it keeps up with european guns but thats respectable. My wolf get groups half that size sometimes, or less!

    Again, do you think Crosman put a match barrel on this one? LOL. i think your answer will be yes, but i mean … match barrel on this one and not the one that i buy!

    one question. If i can use an airforce trigger can i use that one? Im not fond of airforce triggers but they are usable. ??? That crosman is more accurate than an airforce going by those groups!

    I don’t know the gun but I’m technical. could i take it apart and polish it or anything to take some weight off? I did take a course in engineering (but thats on the computer)! LOL ?????????

    -sumo


  29. Sumo,

    Yes, you could use this trigger easily. It’s heavier than the AirForce trigger, but crisper, as well.

    No, I don’t think they gave me a better gun than they are building. My job was to find all the things that needed improvement – they weren’t trying to impress me. Crosman has always been able to rifle a good barrel.

    I don’t think the Discovery is more accurate than an AirForce rifle. I get groups that small frequently. I won’t say all the time, but if a group gets larger than three quarters of an inch, I did something wrong or it’s a windy day.

    The accuracy really surprised me. I was fully expecting 1.5-inch groups at 50 yards and I would have thought that was okay, for everything else that comes in the package. But you don’t have to apologize for this rifle.

    Please remember, though, I did get some groups as large as one inch, too.

    B.B.


  30. BB,

    Looks like more astronomers than I would have thought. Orion is a great place to start IMO. Also try http://www.cloudynights.com if you haven’t come across it. Forums there can be overwhelming, but a great sight for reviews.

    I think the Orion 1/4-20 (camera type plate) to dovetail adapter will work great, too, for a light scope on EQ mount with vixen dovetail.

    Here’s the link:
    http://www.telescope.com/control/product/~category_id=adapters_and_cables/~pcategory=accessories/~product_id=07388

    You can do much worse than CG5 (already suggested)…even lighter would be OK for visual use with small scope. My suggestion would be something small and convenient that will always be handy, realizing that it won’t carry heavy scopes or work for serious astrophotography. I have a Skyview Pro which has been a good general purpose mount (and now has motors and positioning options), but can be heavy for casual viewing and still not anywhere near adequate for serious astrophotagraphy (there are a few, but “it’ll cost you”:)).


  31. Bg-farmer,Sumo,22-multi,Pest be gone,Matt 61,Mec.& others. All need to remember the big African hunt is drawing near!I just completed Bill Dances new Cros. 760- 50 Cal. conversion! Just before I shipped it to him,,,REGRETABLY he called me today, He cant make it!(has to go bass fishin in Fla.)(Okrachoby lake I think) As you know Den. Quack. helped me on this rifle conversion for Bill. The protruding 8″ lag bolt holdin on the yellow pine 2×6 stock tipped w/4oz. of “duct seal” provides a litteral “SPOT WELD”! Set up w/ fully mounted/sighted in $8 Daisy red dot sight, this is one sweet shooter! Me & Dennis worked hard to mod. stock 5 shot clip to accomidate 50 cal.! BB.,Idid not forget you,, Its just that this trip coinsides w/ you being at SHOT SHOW! That is ok,cause next year me & D.Q. plan on having available— The RE-DISCOVERY 50 cal. 760 PCP.!! Anyone interested E.Mail me!Tim.!



  32. I can’t wait to get my paws on the Crosman :-) I’ve been wanting to try a pcp air gun for a very long time and now that there is one within my price range, I gotta get one.
    I’d like to see how adjustable the velocities are for both rifles. Very interested in .177. Really would like to try field target some day.

    Al in CT


  33. B.B.

    OT… I’ll have to agree with the other suggestions of a CG5 for your scope. I just wanted to add another couple of links for you. http://www.astronomics.com sometimes has used mounts for cheap, and http://www.optcorp.com has mounts that have free shipping. Beyond those, you might keep your eye on Astromart and CloudyNights (.com on both) for used mounts, scopes, eyepieces and all that. I just bought myself a CG5 GT (computerized go to mount)from a local shop here in Denver. I also have my 10″ Dob and use Starry Night to locate what I want to look at for the night. I use an old riflescope for the finder on my dob.

    Back to the Discovery. I was disappointed to see that it won’t be shipping until March 8th from PA………….. Sorry for the pause there. Had to wipe tears from my eyes. Guess I’ll live through it though. At the rate new stuff is hitting the market, who knows what else might be out there by then. Maybe that DQ 50 cal 760 conversion will be done first!

    /Shooter


  34. Dragonslayer,

    Of course I’m disappointed that Bill Dance can’t make it — he is one of my long-time, since childhood heroes (true) along with Rowdy Roddy Piper (don’t want to be anywhere near him with a gun, though)–but I wouldn’t miss the trophy hunt for the world. I can’t tell you how happy I am that you got the “7650DS” ready. I had feared I might have to borrow my friend’s surplus 8mm with the iron buttplate. Last (only) time I shot that rifle, I had to have a retina re-attached, and I still flinch whenever I see anything with a Mannlicher stock.

    I’ve sent you a deposit for my 7650 with a satin finished, pressure treated contractor grade stock…I guess that is what you are calling the deluxe version; don’t forget that it needs a stainless lag bolt for the spot weld (great idea by the way). Make sure that the trigger is a good as the one Sumo has — if mine doesn’t break “like wood at 9lbs.”, I will be disappointed. Otherwise, if the red-dot is the fancy one with two-position intensity control, I’d say we’re ready to fuel up the Land Cruiser and head for the watering hole.


  35. sorry bb,

    i would have felt like such a fool spending the money that i had to know! I was focusing on the smaller ones for sure! But the small one was like ave. for me! (its an ego thing LOL)

    A note to all interested in this gun…
    a squirrel can’t tell the difference between a .2 inch group at 50 yards and a .5 inch group at 50 yards!

    BB i tried taking the moderator off the mark one and it was downright violent, almost like a career 707. LOL


  36. Bg-farmer: Just rec. your dep. via. Pay Buddy. Sorry to inform you the “limited ed.P.T. con. grade stock” is no longer available. Due to the recent slump in new home construction scrap p.t. lumber has become scarce! we at Tim Air always wanting to please our customers are now offering a pleasing #6 pallet grade Oak stock at the same price!!Same pleasing satin finish! Inoticed you reqested the upgaded red dot sight system, you will be the first cust. to rec. the new D.Q. Timster AO. tripple bright (adj) red dot!! Am not shipping new 7650 untill mid March to most retail cust. But will ship yours tom. Inc. poly butyl. flexable shroud! Sorry cant ship w/ 9 lb. trig. My trigger specialist just got order for 3 new septic tanks. When he gets done laying pipe we will send you a drop in GRT-9 trig. postage paid!Timster.


  37. BB,
    To think I came so close to buying a RWS 850. Not sure why I waited… but now I might wait a bit longer and check out the Discovery. This sounds very nice.

    OK… the reason for the delay on the 850 was the CO2 in cold weather issue. Which is not a issue for the Discovery. But the discovery is only a single shot and I wanted a multi shot and an simi-auto would be a dream.

    On the whole though the Discovery does sound like it belongs on the short list of must have air guns.

    DB


  38. B.B.

    Before I saw your review on the Benji Disco, a friend and I were drooling over the gun after the review posted on American Airgun Hunter… We went to your blog, joking that you probably had something to do with this guns development…well it wasn’t a joke after all.

    We’re just waiting now for you to tell us that the gun aims itself and knows who shot J.F.K., since it seems to be able to do everything else!





  39. Sumo,

    When I was at AirForce I’d occasionally get a call from a Talon SS owner who didn’t think his rifle was quiet enough. I told him to remove the end cap and check it again. Never got a call back from any of them.

    B.B.





  40. I’m considering this gun to help me solve a groundhog problem in my back yard, but I’m not really familiar with air rifles. I’d normally use a regular .22 caliber rifle, but where I live I’m too close to my neighbors for it to be legal (or safe!). Ground hogs are tough; does this rifle (in .22) have what it takes for one-shot kills, assuming good form?

    Thanks!


  41. BB.,came back to this post to try to slide in “under radar”. Hope you get it. If I ever had the smarts to give airgun advice,NOT! (unless its newbies) Or to start my own blog,NOT! But started my own blog,, for you to even post,, Hi , Multi–I meant Tim,, I would be on TOP OF THE WORLD!! Just a thought. Im just saying, consider it,you are truly a heavyweight in our airgun world! You have real star power & few words from you can make a BIG differance! Thanks BB. Tim.


  42. Hey Dragonslayer,

    My radar scans too far, LOL! Actually I was scanning back as far as the first Discovery post (this post – like BB said, the biggest advance in 50 years).

    BB probably would have said, “Hi.” Unfortunately when he visited, the settings only allowed blog members to comment. I figured that out a little later and fixed it.

    Thanks Tim!
    .22 multi-shot





  43. Did ya’ll notice the new line of Crossman Discovery Hollow Point pellets?

    PA has them (Benjamin-BHP22) listed to start shipping on 2-15-2008. Priced at $10.97 for a tin of 500. Has a screw on lid.

    Something new for B.B. to report on.


  44. if the springs were swapped within the trigger assembly, would it make a significant difference in weight, say, half a pound or more?


  45. Hi BB:
    why in Diana site he listed 22 velocity for 350 is less than 52 while 350 is more powerfull than 52?
    but in RWS site the listed 22 velocity for 350 is more than 52(the way it should be)

    also is it true that euoropian airgun makers weaken the powerplant on their 22 versions which is intended for domestic and asian export?
    Harry


  46. Harry,

    Maybe Diana tested their rifles with different pellets than RWS. Some guns do not do well with certain pellets.

    I’ve never heard of European makers weakening their .22s for export. America is the only country in the world where powerful airguns aren’t regulated by the federal government, so that doesn’t make much sense, does it?

    In their home countries, powerful airguns are considered firearms, and they do not sell them there.

    B.B.


  47. B.B.

    I am itching to get a discovery (or maybe a 397) but on the fence because of the single-shot capacity. You mentioned a new model in an earlier post. Do you know if Crosman has any plans for a multi-shot Discovery? Or any other multi-shot Benjamin in the near future?

    Thanks and great blog!




  48. B.B.,

    I’m going to order the benjamin discovery and had two questions:

    Should I get medium rings or high rings for the scope in order to have ample clearance for loading pellets?

    What adapter(s) or hose(s) do I need in order to use the included pump with my talon’s tank as well.

    Thanks.

    Yes, the Leapers scope you have selected is a good one. With the adjustable parallax you can focus this scope at all ranges you will shoot on the highest power setting.

    When selecting scope mounts you don’t choose them by brand – you chose them by size. Any scope rings that fit the scope tube will work. The scope you have selected has a one-inch tube, so you need one-inch rings.

    With the Discovery you want to use two-piece rings, only. So now you are looking for one-inch, two-piece rings.

    The objective lens on the scope you have chosen is 40 mm, which is reasonably small. So you can use a low or medium-height scope ring.

    Here are the rings I would get:

  50. b.b. I both target shoot, and hunt ( squirrels and small birds crows). Do you think I would be better off with the discovery, or RWS 350 Mag. I value the RWS’s slightly higher power, it’s build quality, and the lifetime warranty. I value the discovery for it’s superb accuracy and lighter weight. Which is more accurate? Also my 14- year old son may occasionally shoot whichever I choose as well, do you think he’d be able to cock the RWS, how hard is it ( I think it says 34 pounds) to cock? Thanks!!!


  51. Bruce,

    Are you talking about a .177 caliber rifle? Because I would seriously consider a .22 for hunting.

    In .22 the Discovery is more powerful than the 350 magnum, and all Discoverys are more accurate than the 350 magnums.

    The 350 magnum is hard enough to cock that neither you or your son will want to shoot it more than 50 times per session.

  52. Stumpo,

    As B.B. said in the comment right above your post, "I would seriously consider a .22 for hunting."

    A Discovery in .22 caliber is a great squirrel gun at the distances that you can consistently hit a quarter size target.

  53. Stumpo,

    The .177 Discovery has enough power to kill a squirrel humanely. But the tiny pellet requires exact shot placement. You are far better off shooting a .22 that has more room for error.

  54. Does anybody know the diameter of the .22 cal jsb exact jumbo pellets that Tom Gaylord used in his testing?

    Were they 5.50, 5.51, or 5.52?
