I have never had one go off when priming cases but do hold my lee hand primer tool facing away from me as I prime cases
I have had one detonate when depriming an unfired primer in a wilson hand loader while I was holding the die
did scare the living day lights out of me and did have to change my jocks
, it wasn't just noisy it shot the depriming mandrel out of the die
the difference when taking out from the wilson to a wobble die is the wobble die pushes the primer out and you whack the primer out with the wilson
I don't do it with the wilson any more but have not had a problem depriming live primers with wobble dies
