I have both the BPI and PRing roll crimpers in 12 and 10ga and prefer the PRing one with 4 pins. It works just fine and I don't slow down the drill press. JMHO, but I think they work better when warm, and the higher speed helps warm em quicker.
Funny, I never thought of using my Sizemaster. Da.

For me it just feels like the 4 pin design takes more force to do the crimp.
I was preheating my roll crimpers but I havnt noticed much of a difference. Im sure the hull type probably plays a part on which method works better.
If I order some brass cases this year though I probably wont be doing much roll crimping in the future. While the initial cost is high they last forever.
I use a 1 ton arbor press for resizing my 8 gauge shells, after firing they dont change in dimensions at least non I could read on a digital caliper.
