These are the crimps I'm getting now. I gave up on the drill press roll crimper, and went old school. The crimper is an old BGI, and is convertible from rounded crimps to square crimps. It takes no more than 5 turns on the crank. The rear two shells are 2 3/4 spent RSTs (Cheddite) trimmed down, and front two are new paper Chedites. I don't heat or treat the lip, and I don't have to use a vise or collet to hold them. It takes about 3-4 minutes to roll 25 shells. I couldn't be more pleased with the results.
