I recently purchased a 1934 Tula, Hex reciever mosin nagant 91/30. I wanted something cheap to shoot and something to practice some basic gunsmithing. So i read a few posts on the internet about how to improve the trigger. Then set about doing them. I started by drilling the top of the trigger and putting in a set screw to push on the sear, then polished the sear and trigger surfaces that touch, to smooth things out. then i drilled out the trigger pivot hole in the reciever and trigger itself because the holes in my reciever were ovaled and had a lot of slop. I then installed a larger pin and put a teflon washer to take up side to side slop as well. I also cut the firing pin spring down a tiny bit to make the rifle easier to cock. Now i have no creep, and a much lighter trigger pull, that's fairly crisp. It's still heavy, i'd guess around 6#. But compared to the massive creep and probably 14# pull it had before it's definitely an improvement.
Now here's my issue. When i bought the gun the bolt cycled easily, now it is very hard to cock the gun after firing(opening the bolt after the trigger has been pulled) I thought it might need lubed, so i took the bolt apart and lubed and reassembled it. Still the same. Then i thought maybe i cut too much off the firing pin spring. So i took apart the bolt and put the piece i cut back in with the rest of the spring. It made no difference. I'm thinking that maybe when i drilled trigger pivot that it moved the trigger up slightly and the bolt stop(top of trigger) is rubbing on the bolt, making it hard to cock? there are marks on top of the trigger that i know are new because i polished it before i put it back together. So now i'm thinking my next step would be to take the trigger out of the gun reinstall the sear and then cycle the bolt and see if it is still hard to cock. Any suggestions would be greatly appreciated. Thanks.
