You should be able to take a knife and cut a small slot out of the snap cap so the extractor doesn't pick it up when you run the bolt back. That way you could recock the gun and snap over and over with out running a new one into the chamber each time.Plastic .22LR snap caps are inexpensive, and easy to use - except, of course, they turn a semi-auto into a straight-pull boltgun.
Absolutely the case, and I've seen a couple that required the chamber to be recut.Never Dry fire a rimfire ever. the firing pin will strike the edge of the chamber and damage the chamber or break the firing pin. It is a no no and anyone who says different has never paid a gunsmith to repair the chamber on his prize .22
X2, good advise.Consult your owner's manual - never hurts to read directions, first
Having said that, I do not dry fire a rimfire unless I have exact information that it is safe to do so. All of my Rugers say so in the owner's manual. In fact, you have to dry fire a Ruger auto pistol to disassemble it.
It is certainly better to be cautious, than pay the repair bill......
I really hate the word "never."Never Dry fire a rimfire ever...
