Accuracy…what should I expect?

    I recently got a Crossman TR77NPS. It came with a 4 power scope and the most God-awful excuse for a trigger that man has ever devised. I'm certain that a chimpanzee could create a better trigger in 15 minutes than Crossman did with this thing.

    I understand that there is a break-in period that might run 500 rounds or so and I'm fairly deep into that period.

    My groups at 20 yards are inconsistent. Sometimes I'll put three on top of each other, then I'll get a flyer about 3 inches away. The scope is tight, I'm shooting off a solid rest, and I'm doing my level best with the pathetic trigger…but I'm not just in love with how the gun is shooting.

    Assuming I get through the break-in period, that I use high quality pellets, and replace the garbage trigger…what type of accuracy I should be expecting from this gun at 20 yards when shooting off a solid rest?

    Spring-piston/gas-piston guns often won't shoot well from a rest. You may find you get better groups by putting your hand under the forend and then laying your hand on your rest.

    High-quality pellets are important, but they are not a guarantee of good accuracy. Airguns can be very picky about pellets. You may need to try a variety of high-quality pellets to get the best accuracy.

    Finally, there is a learning curve when shooting spring/gas-piston guns. Trying to hold them tightly is counterproductive, but consistency is critical.

    This thread discusses some techniques for shooting springers.

    What John said, and minus the fliers I'd say you got lucky in the accuracy dept with that gun. The fliers could be many things from how you're holding the gun/what the gun is touching, the scopes parallax, W/E return spring not holding, the barrel lockup or side washers not holding the barrel the same. Use good pellets with undamaged skirts and seat them the same ea time. Probably more I'm forgetting...
    The trigger can be fixed with an expensive aftermarket job or by doing the work yourself, but to get the best trigger you need to dig in and do it yourself.
    The parallax on that scope is supposed to be set to 100', but I seriously doubt the chinese sweatshop worker sets them right, either way you need to adjust it to your 20 yards. Remember that the gun jumps around before the pellet exits the barrel, so you need to make an effort to make everything interacting with the gun is equal so the gun moves the same each shot. Make sense?

    That's going to take some practice…but practice is fun so it shouldn't take too long.

    I've been looking at aftermarket triggers by a guy name Charlie da Tuna. Sounds like it's a drop in deal for about $30 that gets good reviews. I might buy one of those to start.

    It isn't really very hard to learn, and vary with this sensitivity so it might not be a big deal anyway. And like I said some other things can screw you up like the scope, pellets etc. So how is the shooting going???
    Either of the gold triggers work to make it much better, but you can do the same mod to your trigger if you're a do it yourself kinda guy. There are other mods the gun responds to as well if you're interested.

    Shooting is going good. I switched pellets when I ran dry on the last can. I re-zero'd today and tried to utilize some of the "light hold" technique. The trigger really sucks on this thing so it's tough to keep everything as consistent as I'd like…but using a light hold and a rest up front that allows the gun to slide freely I was able to print some groups that were definitely better than before.

    I'm going to order a new trigger, a variety of pellets and maybe even a new scope. My problem is that I can't tolerate sloppy accuracy…it just bugs me. It's a sickness I suppose…but it gives me something to do and keeps me out of trouble…most of the time.

    Thanks for the help.

    I would hold off on a new scope. I have several of those 4x Crosman Center Point deals and they're all excellent, however I've heard complaints of some with distortion lately so maybe the newer ones are worse? If the picture is clear I'd keep it and fix the parallax, it should be golden after that.
    If still not accurate don't blame the scope right away. Not saying it isn't the problem, but I can say that none of mine are a problem and I've helped many people see the same. The other stuff I mentioned, and tuning helps, maybe the barrel needs a new crown, and sometimes the barrel is junk and you need a new one. They're cheap, ~$16 + $4 ship. Let me know if you plan on ordering, need to tell you some things.
    As for the trigger, hopefully you're happy with it now, but if not I can assure you it can be made as good or better than the gold ones by doing it yourself. For people who'd rather spend the $ then great, but I'm a do it yourselfer all the way and it would kill me to buy one.
    Keep in touch and I'll help however I can.

    Well here is what I achieved with a 'springer' at 25 yards shooting from a rest using a small sand-bag the absorb the recoil from the spring. 10 shots ... I'm beginning to wonder why I'm using good money on .22LR rounds at the same distance when pellets are so cheap.

    Here's the Gun:

    It's marketed as a Weihrauch HW97K over here. A heavy rifle at 4.2kg which is why I tend to bench-rest it if shooting for sometime. It is especially developed for field-target and silhouette shooting and I've won a few competitions with it. It's well-balanced and built and easy to cock with a beautiful stock.

    I'd highly recommend it for both target shooting and plinking.

    The stock IS very nice. It's definitely a big improvement over what used to come on the older HW97s from Beeman.

    Many crosman triggers have a screw behind the trigger to adjust it. the screw is to short. I think it is an M3 or M4 just bring it with you and get the next bigger one. You will be able to take out the long pull and shorten it to what you like by screwing it in further then stock screw. Be careful not to over do it .The rifle could go off when cocking

    Just as a comment, Springers can be exceptionally accurate.


    This is the factory target for my Beeman 400. 10 shots at 10 meters by the way.

    Yes, springers can be very accurate.

    I have a Baikal IZH61 with an aftermarket diopter sight, and it stacks pellets out as far as you can judge the drop.
