To have a round go off while reloading. That is, it's not in the gun. It may be in a die. I was thinking about a round stuck in a die with primer and powder. Seems to me you should not attempt to get it out. Just order a new die and get on with life. Or as someone said, what if, you try, mistakenly, to seat a primer with powder and a bullet. Any known statistics on how many people have a serious accident per year from hand loading? I am wondering how dangerous this really is (per hour vs, say driving per hour, or motorcycling, skiing etc) Sorry for the morbidity. I used to be a safety officer.
