Today we test the velocity of the Kral Puncher Breaker Silent Synthetic bullpup rifle. Let’s begin.

Magazines are easier to load

I found the two magazines that came with this rifle MUCH easier to load and manage than the mags I tested with the.22 caliber Kral Puncher Pro rifle last year. That one gave me numerous failures to feed in the velocity test. This one was perfect! And, when I say one, I mean that I tested both mags. It also loads easier, because I think the spring in the mag may be lighter. At least that’s how it feels.

Crosman Premier Lights — low power

I used the Crosman Premier Light pellet, to test the range of power adjustments. I started with 10 pellets at the lowest setting. They averaged 356 f.p.s., which is very slow. The low was 349 and the high was 365 f.p.s. — a spread of 16 f.p.s. That’s pretty tight for the absolute lowest power setting.

At the average velocity on low this pellet and setting gave me 2.22 foot-pounds at the muzzle. The discharge sound was extremely quiet. No neighbor farther than 25 feet will even notice it.

Crosman Premier Lights — medium power

Next I dialed the power knob to the mid point. At that setting 10 Premier Lights averaged 778 f.p.s., with a low of 771 and a high of 784 f.p.s. That’s a spread of only 13 f.p.s.

At the average velocity this pellet and setting gave 10.62 foot-pounds of energy at the muzzle. The discharge sound was high — almost a solid 4 on Pyramyd Air’s 5-point scale. You should not shoot this in your back yard if you have sensitive neighbors. At this power level the Puncher Breaker Silent Synthetic lost its silent rating.

Crosman Premier Lights — high power

The power knob was dialed up as far as it would go. At that setting the rifle averaged 1086 f.p.s. with the Premier Light pellet. The low was 1072 and the high was 1094 — a spread of 18 f.p.s. The rifle is still consistent at this power setting.

At this velocity the Premier Light pellet generates 20.69 foot pounds of energy at the muzzle. The discharge noise is in the high 4s — a rifle that will draw attention from 100 yards. There are louder smallbore PCPs, but this one is loud. It’s completely different from my experience with the Puncher Pro rifle in that respect.

Discussion

Looking at the power settings and their velocities I know there are a lot of other settings that will give you exactly the velocity you want with this pellet between the absolute low and high. If it were my rifle I’d find the best pellet and velocity and leave it set there. But there is more to see today.

At this point in the test the onboard gauge still indicates 160 bar of air pressure in the reservoir. I began the test with 200 bar in the gun. I have fired a total of 35 shots at varying power levels so far.

The action is not stiff like the Puncher Pro I tested last year, but there is resistance to the cocking lever as the bolt is pushed forward to seat the pellet. I thought it was the magazines, but when I tested the rifle with no magazine installed, I felt the same resistance. It’s something to get used to, I think.

Also, because this is a bullpup, the cocking lever is back by the buttpad. That puts it at your shoulder. It’s not convenient to cock when it’s resting on your shoulder, but I will look closer at that in the accuracy test that comes next.

High velocity

Okay, what’s the mostest-fastest velocity we can get from this Puncher Breaker? I’ll use a synthetic pellet and it’s going to break the sound barrier which will add to the discharge noise, so I’m only shooting five shots.

I selected Sig Match Ballistic Alloy pellets for this test. They weigh 5.25-grains and should give really high velocities.

Five Sig Match pellets averaged 1191 f.p.s. The spread was a tight 3 f.p.s. — from 1190 to 1193 f.p.s. They definitely did break the sound barrier but my tuxedo cat, Punky, slept through all of it in my office. I even warned him before I started but he just looked at me with one eye open and then curled back up. I thought the shots were very loud, but Punky obviously didn’t agree.

At the average velocity this pellet generates 16.54 foot-pounds of energy at the muzzle. It’s demonstrating that light pellets are less efficient in PCPs.

Max power

Now that we know the velocity, what is the highest power the Puncher Breaker Silent Synthetic can produce? I didn’t use the absolute heaviest pellets possible, but chose a standard heavyweight that most shooters might use in a rifle like this — the H&N Baracuda Match pellet. This 10.65-grain pellet averaged 979 f.p.s. on high power. The spread was 8 f.p.s. — from 976 to 984 f.p.s. and the energy produced at the average speed was 22.67 foot pounds at the muzzle. The heaviest pellet you can find might bump that up another 1-2 foot pounds.

At this point there are 45 shots on the fill — and 20 of them were at full power. The manometer now reads 150 bar (2176 psi). Like the Puncher Pro, this rifle seems to manage air well.

I loaded another magazine of 14 Premier Lights and shot them next. The rifle is still on high power. The first shot went out at 1161 f.p.s., which is 25 f.p.s. slower than the maximum average velocity with this same pellet. The 14th shot went out at 987 f.p.s and the average for this string was 1024 f.p.s. Clearly the rifle has dropped off the power curve. You can still shoot for awhile, and if you are shooting at lower power it should be possible to increase the power setting at this point to keep the velocity the same. That takes a lot of experimentation with one specific rifle and pellet. I had a Career 707 I got to know very well and could get 90 shots at 30 foot pounds if I kept dialing the power up as the number of shots increased.

The rifle’s gauge reads 130 bar (1885 psi) at the end of this string. I refilled the tank and noted that the actual pressure inside was 2,000 psi on my tank gauge that is fairly accurate, so now I know where the onboard rifle gauge reads. It’s only off by 100 psi, which is pretty accurate. The needle is still in the green at this pressure, but the rifle is definitely off the power curve.

Trigger pull

The two-stage trigger is reasonable, if not light. There is some movement in stage two, but I wouldn’t call it creep. It’s smooth right to the letoff, which comes at 4 lbs. 5 oz. I can live with that.

Next

I start testing accuracy next. I am already looking at this little rifle fondly for its light weight and compact size. If it turns out to be extremely accurate, Pyramyd Air may not get it back!

  1. B.B.,

    Does this cock on opening or closing? How much Force is required to cock this? From the way it is performing the transfer port is certainly the one being manipulated by that adjustment screw. Seems like they were understating the power output claiming only 18fpe, while you were getting 22fpe with a pound or two to spare with an even heavier pellet.

    This one certainly is something to look forward to in the accuracy test.

  2. Hi BB et al..
    Well, I guess it’s now official – I went to the dark side.
    I picked up a belated Christmas present from Canada Post this afternoon. A Beeman QB Chief .22 cal. and hand pump combo which I had decided was to be my initial foray into the world of PCP guns.
    After getting the rifle and pump out of its “shipping container” – it was really well packed, I got it out of its box and I have to say it is a nice looking rifle. It came completely unloaded, that is no air pressure at all, so my first order of business was to get the hand pump assembled and tested and get the gun pressurized. It seemed to test OK up to the recommended 1000PSI but when I began pumping up the gun and got it up to 2000PSI on the gun’s gauge the pump gauge only read 1000PSI.
    I did a dry fire test and the gun seemed to work fine – no sign of lockup so I think the gauge on the gun is fine. My thinking is the pump gauge may be defective or possibly needs a little break in period. Tomorrow I’ll send an email to the vendor to see what he thinks.
    BB – I’m curious to hear what you think about this.
    Apart from that small problem I am impressed with the gun. Although the stock is a little too matt finish for my taste the wood is quite nice with no fillers at all. I think a few coats of paste wax will shine up the laquer to my liking.
    Tomorrow I’ll try shooting it on my indoor range but I think I’ll have to get a .22 rimfire trap in order for this to work. As I remember from last year the Browning Leverage with a bit lower MV and lighter pellets was starting to take my Gamo pellet trap apart.
    Why not just take it outside you say. Well the high today was -24°C, currently -29°C and a forecast low tonight of -32°C (-26°F) and about the same for the rest of the week!
    I’ll be waiting for a Chinook before outside happens!
    Cheers – Dave


    • Redrafter,

      Welcome to the PCP world. I hope it is everything that you hoped it to be. Bummer on the pump gauge. At least the pump works and the rifle does, so that is a blessing.

      On traps, I have 2, both homemade from small crates. They are 1/2″ OSB board, all 2×2 inside framed and have a 11 gauge steel plate in the back. Cut out the front, hang the backer, good to go.

      -26 F,… eeeek! The lowest thus far in Ohio this year has been -14 F.



    • Hi Dave,

      Congrats on your first PCP! Its a great time to be exploring the dark side as there are lots of options at reasonable prices.

      I am resigned to shooting my 10 meter stuff indoors until mid-March at best. We have just come out of several weeks of -25 to -35 C to have two days of above freezing temperatures, high winds, freezing rain, rain with a promise of a flash-freeze tonight and a major dumping of snow. Gotta love weather in Canada eh? Don’t like it, wait a minute and it will change LOL!

      Hoping you get a couple of good Chinooks Dave!

      Hank


    • Dave
      Glad your giving pcp’s a try.

      And you should know which gauge is accurate when you start shooting. If you only get a hand full of shots before POI starts to drop then you know your pumps gauge is right. If you get a bunch of shots then you know your guns gauge is right.

      And got to ask. Does your gun forward cock. My QB79 does. The bolt clicks back fairly easy. Load the pellet then there is spring resistance when you push forward. At first I didn’t like that. Over time I have become use to the feel of a pellet loading when the bolt is pushed forward. In other words I can tell how the pellet is fitting the barrel. It takes some getting used to on the forward cock of my QB79.

      And how’s the trigger. Mines a single stay. A very smooth pull basically no feel really other than spring pressure. You pull and the shot breaks. There is no spring pressure adjustment but I did lighten the trigger pull in mine. It’s super light now. Almost like a FWB 300 trigger adjusted to have no first stage and on the very light side. The gun actually shoots very well for a $100 gun.

      I’m thinking of your Chief is alot like my QB79 other than yours has a air resivoir tube and mine accepts a bottle.

      But glad you got it. Interested in hearing more.


      • Hey Gunfun1
        I will be checking out the gauge problem more this evening. Only about 15 shots so far into the rebuilt trap with about 1250psi left from the original fill of 1900psi. Looks like it may get the advertised 20 shots which will indicate the gun’s gauge is reading correctly.
        As for being similar to the QB79 I think maybe in name only. To start the receiver is a completely different size, about 1inch shorter than your QB79 receiver. It has a rearward cocking bolt so no resistsnce when loading a pellet and the iron sights may be different as well. They’re all metal with very fine fiber optic inserts. The stock is ambidextrous with raised cheek rests sculpted on both sides with a rubber butt pad and about a 14″ pull which is perfect for me.
        The trigger is two stage and completely adjustable. Feels like about 3 to 4 lbs. Out of the box the only thing I don’ t like is the too short first stage. The pull weight and overtravel are just about perfect for me. The first stage pre-travel at about 1/16″ is way too short for my use. But being fully adjustable that will soon changeto about ¼”. Even with the short pre-travel I can still feel and stop the trigger at the start of the second stage. Then it’s just “breaking the glass rod” thing to actually fire the rifle.
        As well the gun comes with a degassing tool just in case it ever gets over pressured and locks up.
        Soon I’ll be mounting a scope – I have a brand new 6x24x55 AOE MD scope that I hope I can fit on the gun.
        And, just like about every other airgun in the world, there is a breakin period to get the gun shooting properly. The general consensus from what I’ve read and watched on YouTube is about 450 shots required to break in the valve. What that means is with the trap working properly now I should be able to break in the rifle on my indoor range this winter and have it ready for the spring shooting season.
        Cheers
        Dave


        • Dave
          It sounds like they are two different guns to me. And I like a long first stage too on a two stage trigger.

          And you should be contacting who you got the pump from. At the least they should be sending you a new gauge.

          And guns do seem to get better over time. But then again. Some never do.



  3. BB,

    I myself have never been a fan of the ad hoc bullpups. They seem to me to be a cheesy marketing scam. “Let’s get in on the bullpup craze! With the minimal investment of a different stock and a push rod, we can take our air rifle and have a “new” model to market at a higher price!”

    I also am not very much of a contortionist. Trying to work that action while it is on my shoulder is almost impossible for me, even from a bench rest.

    Don’t get me wrong. I would very much like to have a bullpup, but I want one that was designed to be a bullpup from the start.


  4. Very interesting. This one is a bit of a standout in the looks department. The low power does seem too low, and to be that loud at medium power (compared to all the other shrouded PCPs out there) seems to make the gun name a bit misleading.

    We have not seen feline intervention in any recent blog photos. Punky, where has your curiosity gone? Maybe he’s just used to it. I can’t do anything around the house without feline supervision (“I’m sorry, my cat jumped into the open computer while I was swapping your RAM out and the static charge shorted out your motherboard.” Okay, I’ve never actually had the shorting-out happen, but I have gotten the jumping-in-the-computer.) We’re down to 2 cats at the moment; how about the Gaylord household?




      • My wife and I have two litter mates, Ben and Jerry. No, that isn’t any sort of political statement. Ben just looks like a Ben (think a black bear, “Gentle Ben”), and Jerry looks like a Jerry (think a young, skinny Jerry Lewis). Ben was the big boy of the litter, and Jerry was the runt. I admit there might be a bit of an ice cream reference, in that they are soooo sweet. Each insists on being picked up and held a dozen or more times a day, and they nap all over us (and each other). They are also both real talkers.

        They have been responsible for making every single “I don’t like cats” guest of ours into a “Well, I didn’t know cats were like this” person.

  5. BB,

    Your gun may be defective. I’ve seen video reviews online, although in .22 caliber and outdoors, where a sound pressure meter was barely able to distinguish the gun’s report on high power from ambient noise. The reviewer commented that it sounded very quiet to him as well. Is there any reason that a.177 should generate more noise?
    The pellet was sub-sonic on medium power, for certain. Will you give us your impression of the noise when you do the outdoor accuracy testing?


  6. BB,

    One reviewer even mentioned that he had the shroud apart and found nothing much to speak of inside, thereby making it easy to clean the barrel if you felt a need to and that in spite of that it still did ” an amazing job of quieting” the gun. His gun also averaged over 29 foot pounds over all the pellets that he tried on high power and over 19 foot pounds on medium, if sub 12 fpe is what you meant by European. Maybe it just sounds loud indoors. I just wanted to point out the possibility that your’s could be defective because of the discrepancy.


  7. “I thought the shots were very loud, but Punky obviously didn’t agree.”

    Hahaha! On the next test, I’d like to see a pic of Punky sleeping next to you while you fire the gun. =)~


  8. B.B.,

    My mind reels at all the air rifles available from different parts of the globe.

    This morning I want to share a couple of pictures. For the past week I have been trying different pellets at 50 yards, while attempting to keep all other variables a near to same as I am able to pull off. Both sessions were 25 pellets, give or take one.

    The first photo may have been Gamo Red Fires, I’m not sure. I do know that the Crosman and Benjamin .177 hollow points both shot to the left of my aim point and slightly low. The same was true for the Premier Copper Magnum pellets. Even so, the was nothing I could call a group of any consequence.

    The second photo was shot at 50 yards with Premier Pointed 7.4 gr. pellets. Not great, but definitely different. There is one large cluster and one small cluster, as well as a few satellites. At first I thought the pointed pellets shot better at 50 yards than anyone said they would; this is the reason I am only just now trying them out. But then I thought. I have been shooting pellets at 50 yards for a week. I have no idea how any of the other pellets would shoot if I shot only them day after day at 50 yards (working on keeping everything consistent). I suppose I will have to take that under advisement.

    ~ken




      • Ken,

        I have not shot much with .177 at 50 yards but I had one tin of Crosman pointed pellets in .22 caliber that that were extremely accurate. The next tins I bought were not as good. So they can be very good but I think they are very difficult to make with good controls on tolerance.

        It sounds like you have tried quite a few pellets. I have had best luck with JSB pellets at long distances. Didn’t you just get a new gun I forget what it is. I am sure others here probably can provide some other ideas on pellets.

        The sub groups with the pointed pellets show that you and the gun can get great groups at 50 yards. You just need to find “the” pellet and tune for that gun. It can be very frustrating I have been there a few times.

        Good luck,
        Don


        • Benji-Don,

          Thank you for writing. I have been shooting my .177 Crosman F4 (which I suspect is just one of a few cosmetic variations of the same power plant). This is a rifle that retails for around $90.00 US. By no means is this a “hi quality” air rifle. At best it is a plinker, but I want to get the best it will do. I bought this rifle specifically to use at our “once a month” group. I have been able to get better results with this one than with my .22 Titan or the Hatsan 70 (it has the old trigger made of laminated steel parts and impossible to adjust to any reasonable pull; I shoot it at 20 to 30 yards for minute of tin can purposes).

          As for the JSB pellets, take a look at this. He starts talking pellets right at 6 minutes and gives us a laugh as well as advice on pellets.

          • Ken,

            50 yards is a very respectable testing range. I do most of mine at 30. That extra 20 opens you up to more wind and other variables and can lead to more questions than answers. Nice link. I watched the whole thing. I love that guy. A real hoot! Quite the impressive range he has too. I bet that plastic covered “tunnel” is an indoor range.

            My vote for the JSB’s as well. I am not sure that pointed and hollow points are your best choice at 50 yards. Actually,.. I am pretty sure.


            • Chris,

              That gets me back to the beginning. How well can I shoot the Crosman Copper Magnum pellets, which are domed;TwoTalon has written that those are not well made, though. I will have to start over and shoot them steadily for a week or two. I think purchasing some JSB pellets will be of interest. I know there is more than one to try out.

              I also enjoy watching Giles Barry; funny, and a great shot I think. There is an episode where he is visiting in Arizona and makes some 200 yard shots (PCP, of course).

              I also shoot at 30 yards (my back yard range limit).

              ~ken


            • Chris,

              We are used to the Airgun Lodge on Airgun Reporter, but this one is probably for starting plants that will be transferred to the field later. This video, another from Britain, starts off with some shooting inside a plastic covered Quonset hut. These two guys shoot a lot, shoot well, and can make some long shots with their sub 12 fpe rifles.
              https://www.youtube.com/watch?v=4F60e15_WiA


              • Ken,

                Very nice. Good bird hunting video. The plastic covered tunnels looks to be able to be used for both,… growing and shooting. A plain A-frame would be easy. Plastic does not hold up well to U.V. though. Wind worthy would be another consideration.

                I admire your determination to sticking with 50 yards.


        • This is an awesome test you conducted. That reflection that you, the pellets, the gun, and the range have been working together for a week, is probably influential. Basic domestic Crosman pellets do well sometimes!


      • Ken,

        I just figured out you are probably shooting the Crosman F4.

        Those are good groups in my opinion with that gun. Obviously you are getting the artillery hold down. It will be interesting to hear how it comes along with more shooting and more pellets.

        Don



        • Don,

          I will continue to practice at 50 yards. Of course I will shoot at closer distances. I do believe I I can shoot at 50 decently I an shoot at closer ranges. I know there is no guarantee, but the subject of JSP pellets comes up too often to ignore.

          ~ken


  9. Hi Chris
    My trap is made from an old “Tall Boy” folding kids desk. I took the upper cabinet and converted it to a trap with 2 pieces of conveyor belt for a backstop. The front rubber backstop is curved and mostly reflects sub 500fps bb’s and pellets into the lower part of the upper cabinet. The occasional bb did bounce out a couple of feet and higher velocity pellets embeded into the rubber. A couple of months ago I placed a piece of ⅛” steel plate about 14″ x16″ over the center part of the rubber at about 28° faceing down and so far everything is reflected into the lower cabinet into an old quilted moving blanket crumpled into the space.
    Since the steel plate install nothing has ever made it out of the trap. .177 pellets leave a grey spall and steel bb’s leave a little pock mark. Airsoft bb’s break up but are caught up in the blanket.
    I’ve just put 20 shots from the QB Chief into the trap with no problems at all. It’s nice to know the trap will handle .22 cal at 850ish fps now.
    Check out the attached photos of the old desk and the steel plate. The small grey splats are .177 pellets. The bigger splats are .22 pellets just now from the QB and the tiny shiny divots are steel bb’s, mostly Hornady Black Diamond at around 350fps to 450fps.
    Cheers – Dave



    • Redrafter,

      That second one looks familiar. Your set up is nice. I am surprised as it seems you use no backer for the target. I use 1/4″ hard rubber matt too between the target backer and steel plate. 1) It slows down the pellet and 2) it acts as a rebound safety for anything wanting to bounce out/back,.. never an issue. For .25 M-rod chrony work at 5 feet,.. I use some 2x in front of the plate. It ate through eventually, but then just started a big ball of lead. I will use hardwood 4×4 next time.

      BIG tip for isolating noise of the plate. (Fully) isolate the mounting points with foam and/or rubber.


      • Chris and Redrafter,

        I have nothing over 25 fpe., but I have a homebrew bullet trap I picked up (with difficult as it weighs well over 100 pounds) at a large flea market. I bought it from the professional welder/hunter/prepper who designed it and made it and whose wife was making him sell it. (She was there and corroborated him.)

        It had no parallel sides, no right angles, and was welded on both sides of each seam. The panels for the lead tray and the legs were made of 5/8 inch steel. The outwardly angled panels were 3/4 inch thick, and the rear panel, angled downward (25 degrees, maybe, I should have asked) was 7/8 inch steel. Nice thick handle for tipping it to empty the tray. It has a large tray, but I empty it pretty frequently because I don’t want it to get too heavy to tip.

        Thing is, I have it in my 10 meter basement range where it serves both as my pellet trap and a conversation piece. And in the basement it shall stay unless whoever owns our house after us dares haul it up the stairs.

        The maker/seller told me he had shot “high-powered centerfire rifles” rounds into it at short ranges with no issues. Iasked him for specifics, but then he stopped smiling and said he didn’t talk about what he has. I nodded respectfully, trust me. :^)


        • I should have mentioned that I never weighed the bullet trap, it is simply not possible that it weighs under 100 pounds. My best guess is between 175 and 225 pounds empty.

          Nope, never measured it, and how it is situated, I couldn’t get too far beside it, much less behind it. I’ll measure the opening and (approximate) inner depth after I finish getting my basement rearranged.

          Michael


          • Michael,

            Impressive story. That sounds like a co-worker of mine, now passed. The stories are endless. He went as far as to making LDC’s and would fire in his basement as well. R2BARMS license plate on Jeep. He liked to drive through town with the top off and 6 high powered rifles strapped upright to the roll bar in the back seat. Did (very long) shots at ground hogs. Plenty of pics and 2 other co-workers to back him up, both similar, but not quite as “nuts” as this fellow was.


  10. B.B.,

    “I had a Career 707 I got to know very well and could get 90 shots at 30 foot pounds if I kept dialing the power up as the number of shots increased.” That is an idea that never would have occurred to me. It is brilliant. (Not that an idea need be brilliant to be beyond my mental abilities.)

    It is also perhaps the single best argument one can make for PCPs having a many-stage power adjuster. Consider a PCP that could adjust with five or six power settings providing a wide range of muzzle velocities. The Evanix Monster lacks power adjustment, but if it did, say six power levels going down to .177 Premier Lights at 350 fps., might a .177 Monster (with its 1760cc hpa capacity) get 1500 good backyard plinking shots per fill using the method you described? 1800 shots per fill? (Evanix claims 245 full power shots.)

    Michael


    • Whoa! I just realized I misinterpreted Evanix’ webpage for the Monster. 960cc max fill and 135 shots at full power. So, 1000 2 fpe. shots per fill if I it had a really, really low-power regulator?

      Michael



        • B.B.,

          For a while now I have thought that the air rifle market needs a PCP equivalent of the classic version of the Diana Model 27: light, adult LOP but otherwise on the small side, low-powered, quiet, easy to cock, accurate, 2000 psi fill, impressive shots-per-fill, and an excellent trigger.

          There are a few out there now that have a number of the above characteristics. The Maximus Euro fits everything except the excellent trigger. Of course there are tuners who can lighten it some and perhaps make it more crisp.

          Michael



            • B.B.,

              From a marketing perspective, and there’s certainly nothing wrong with profits, they might be right. Perhaps the thing to do is to select the PCP closest to what I described, such as the Maximus Euro, get or do a trigger job, and invest in a power reducing regulator. Crosman claims 65 shots and 12 fpe for the Euro. I would prefer something more like 7-8 fpe and 90-100 shots.

              Then again, one might simply ask, well, if there is/was such a thing as a Diana Model 27, why not just get one of those instead of going through the trouble of cobbling a PCP equivalent? The only response is recoil. How much recoil does a vintage 3 ball bearing trigger 27 have?

                But the thing is. Everybody don’t want to use the gun in the same way.

                For the most part they try to design a gun that covers the general function of a gun.

                The added things is what always seems hard for the manufacturers to build.


                • Gunfun1,

                  One should use the right tool for the job. Don’t use a 28 ounce hammer to do upholstery work or hang picture frames. Don’t use a tack hammer to drive big nails.

                  A general use air rifle is doomed to do everything, but poorly, and to do nothing well.

                  If I hunted small game, I would want an AirForce Condor in .25. To shoot aluminum cans from my patio, give me a very small and lightweight .177 shooting at 550 – 700 fps. I have a TX in .177. It is perfect for shooting at the Campbell’s logo on their large soup cans right up against our perimeter berm from a bag on my patio table. I screw the steel cans from the bottom onto a 2 x 4 and then fill them with playground sand. The sound the pellet makes is as satisfying to me as the sound of a basketball fired from the three-point line swishing through the net or the crack of a bat echoing in a major league ballpark.

                  But each is a tool for certain jobs.

          • Michael,

            It does not take a tuner to work on the Maximus trigger by a long shot. GF1 would know, but there is trigger group upgrades from other stock Crosman/Benjamin air guns that will swap right in.

            A weaker hammer spring might do the trick on low shot count and low fps/fpe. I do believe GF1 has a lighter spring in his. On regulators, I am not sure of how wide a range they can work over. The Maximus is ideal for a light and good looking single shot. It could be a great base to build from. LOP might be a bit short, but a LimbSaver butt pad slip on (+1″) put it right at 15 1/4″.

            Optimally balanced parts in the valve as well. What you are asking for may take different valve parts. I am not sure is reg. is needed if they perfect that aspect.

              The Discovery and Maximus triggers are junk.

              Seriously think about the trigger on your Air Arms Tx 200.

              That trigger blows your Maximus trigger away. And that’s not even close to the best trigger. Get you a FWB 300 and then you will know what I mean.

              You can only improve something so much. If you keep trying to improve. Sooner or later you may as well of started out designing something better from the start.


              • Gunfun1 and Chris,

                I have a TX200 and an FWB 300s. Just incredible triggers. They spoiled me for anything else. But my FWB 601 trigger! It can be adjusted in every manner one could think of. The face of the trigger has infinite adjustment for how far to the left or how far to the right it faces!

                I have learned to love the two-stage trigger which is set to perfection, so you can, as B.B. puts it, stop at the second stage and when you’re exactly on target “think off the shot.”

                Michael


            • Chris,

              I know there are aftermarket triggers for the Crosman 2240 and 1377 pistols. I don’t know how decent those get. To be good enough, I would want to end up with a trigger that is two stage, reasonably crisp, and light. Adjustability is a plus.

              I wonder, would switching out the hammer spring for something lighter also lighten trigger pull?

              The thing is, by the time one replaces the trigger, replaces the hammer spring, and installs a low pressure regulator, he is left with a Maximus that cost $500. If that’s what a nice PCP version of a Diana Model 27 would run, I can wait a few more years (or even forever).

              Michael
