My dad found a pretty nice condition Remington model 12 22LR pump. Everything is good, although one out of 5 rounds do not extract from the chamber. The extractor looks in good shape, and I think it is peening the chamber from dry firing that is causing the issue. Brownells used to have a 22lr chamber iron, but I haven't seen them lately. I figured it would not make it worse if I was careful. Anyone have one I can borrow or buy cheaply?
