Her is why, the firing pin on these firearms is made out of a harder material then the chamber or barrel itself and that is done on purpose.Whenever you're firing pin on a rim fire or firing cartridge hits the rim of the cartridge it hits the rim and that brass rim is soft so that is going to absorb the blow of that firing pin. If you are drying firing it that firing pin will be slamming into the edge of the chamber. When it does that since it's a harder material it's actually going to be pinging the edge of that chamber and that is going to lead to failure to extract. Failure to feed. different issues like that and make it hard to fire and will damage the firearm.
