Now I'm really confused. I plan on buying a Ruger Blackhawk with convertable cylinders, .45 ACP & .45 LC. If I purchase a set of dies for the 45 ACP wouldn't they be taper crimps, but since the round is being used in a revolver, shouldn't it be a roll crimp?:banghead: The .45 LC will take care of itself because it's made for a revolver, but what do I use on the ACP? Will a strong taper crimp be OK even with hot loads? Helppppp!
