I'll drink to that, but be careful with a live primer in a case in a vice with a steel punch blow it CAN indeed make it go off.
Also with more powerful shotgun primers(410) it can blow back and the caspsule can actually come out of the case(+sparks and dust), maybe because the cup/anvil assembly is sometimes a looser fit and bigger than rifle centrefires?
That's when you need gloves and eye /ear protection !
