The best thing I've found for crimped primers is the Lee Depriming die. That thing is tough. Mine has deprimed thousands of crimped .30-06 cases and a huge amount of 5.56 crimped brass.
It has survived the occasional Berdan-primed '06 case. Helps keep my Garand and O3A3 fed.
I think you should at least take a look at it.
