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
think about this... you're going to ream a chamber out of (making the walls thinner) something that is only meant to hold enough pressure to get a 28 grain air rifle pellet up to 650fps. that's a muzzle energy of 26 foot pounds. that's 1/3 the energy of a .22 short. also, keep in mind that the impulse from a smokeless or black powder detonation is way higher than just pressurized air.
This is true.. I hadn't thought that they probably used a much softer steel. So basically all I have is a long piece of scrap at this point. .
