Free: Contests & Raffles.
I've deprimed lots of live primers with no detonations. The key is to do it SLOWLY. Primers are actually pretty stable, and it takes a quick strike to set them off. Do not try to do it with a hammer and punch. A friend of mine tried that, and it's a good thing he had thick calluses on his fingers! I only use an RCBS hand priming tool these days. It's so much easier and faster than the old ram method.
