A pox on you, Hiram Berdan! Just working through a bunch of tumbled 9mm brass from Wes and with about 30 pieces of brass to go, I ran into one of those beauties. Luckily, I was using a Lee U die and the depriming rod just pushed up out of the die as designed...no broken pin. First one of these I've ever run into, but I just recently started reloading 9mm...maybe I've just been lucky with the tens of thousands .223/5.56 I've processed.
