Teddy12b, if the previous rounds had the primer knocked out, the pin would still be in the die. The only loaded round, that the pin could possible be in, would be the last round that the old primer was pushed out, and a new primer pushed in. My guess is, the pin is in the case that the primer didn't get knocked out. Do you have carpeting around your loading bench? I have a 3'x4' thick piece I stand one, and I found a live primer in it once, when I ran the vacuum cleaner, and the primer exploded in the vacuum cleaner. Not sure who jumped the highest, me or the dog. I wouldn't worry about it to much. We keep trying peace, it usually doesn't work!!Remember(12/7/41)(9/11/01)gypsyman
