So I have a pelletgun I use for getting squirrel tendies in the yard and shooting shit birds that land near. Hatsan 95 in .25 caliber. Well it shit the bed, and it was cheaper to just get a new one than try to replace the piston. I know, get out of here with that airshit. The gun is useless to me now, but the barrel is still good. I was thinking of taking the seals out, putting a bolt on the piston for a firing pin, reaming out a chamber. I just don't know what cartridge would be good to do it with was looking at a rimmed cartridge to make headspacing simpler and possibly extraction. I'd ask a gunsmith forum but they would tell me to never even consider it. Obviously going to test fire remotely. I thought you retards might help me out.

TL:DR=My pellet gun broke, what .25
