These have a crimp groove so no problem with 45 Colt in a revolver/ But for the 45 ACP and taper crimp. How do you adjust the crimp so it doesn't go to far in the crimp groove so the round will still headspace on the case mouth,? I used the MBC version years ago but do not know if they were spacing on the extractor??
