Thread: .22 issue

Is there a visible mark on the breech face where the firing pin hits? Could be peening of the chamber edge from dry firing.

Check what gundoc said. I use some kero or meths and get a toothbrush or you can get parts washing brushes like them and give the front of the bolt a good scrub. Even soak it first

Yes that’s what I think, many moons ago my old departed mate had a BSA 15 shot which started doing the same , shells stuck after firing.
On inspection there was a burr on the edge of the chamber where the firing pin was hitting when dry fired. Some new rifles especially semi autos can tolerate dry firing but it’s not really a good thing to do with a rim fire.

If there is a firing pin indent ( dont dry-fire your rimfires folks ) you can gently reshape the roundness by tapping a tapered punch into the chamber. A nail punch will suffice - you are wanting to restore the roundness of the chamber mouth.

You can get proper chamber iron tools but my nail punch woks more than adequatley...

I made a 'proper' chamber iron a while back, and sent it to another member here once I'd fixed the rifle I was working on. He'd probably send it on if that is indeed the problem here.
