Re: You can snap on an empty case once or twice...
At the risk of beating a point to death, and venturing into the always hazardous world of metalurgy, it would seem that a hard (brittle) piece of steel like a firing pin would be an all or nothing proposition. Either you fractured it or you didn't. The number of dry fires would seem irrelevant. It is not a piece that flexes like a spring.
Or is it possible to create some minute stress fractures that eventually lead to failure.
Thanks for the erasure idea John.
