These are my 2.5" ITX loads for waterfowl. BPI roll crimper, I bought a 12 and 16 at the same time and they sent a little tub of anti seize compound for bolts to lube them with, now I just put a squirt of oil on the drill press base and dip my finger in it every once in a while. I do use junk shells to warm the roll crimper..
When I run the crimper down over the shell I stop when it hits the plastic and hold it there with slight pressure and there is a moment when you can feel the plastic start to give and then just smoothly run the crimper down.
A little spring loaded shell holder I made, I have leather spacer for it to do 16ga.
