12. Seating and Crimping in one single step! (beware, not always desirable)

One thing that can really save time on a single stage press is having the ability to seat and crimp in one step. I have found that when performing a roll crimp with a cast bullet that boast a generous crimp groove, this is a great option. It isn't complicated, but there are some things to be aware of before proceeding. Some bullet profiles will not agree with this method.
