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.
Read a bit more carefully man, I didn't realize while the primer seater was tucked in the case holder that it was flipping the primers. I watched them go into the ram the correct way and watched them come out upside down. I figured out to not try to prime unless I rechecked the primer if I heard or felt the spring that holds the primer in place go twang. Every round I charge is done on the scale and usually triple checked. I like my guns too much to do anything to jeopardize them. My face wasn't that great to start with though so I'm less protective of it.
