michaelprob: I use the Lee Factory Crimp die and it works very well. Did not think a roll crimp would be effective with jacketed bullets.

It isn't. That's why I have to be careful how down far I set the RCBS die. I'm making up 100 more with a COL of 2.20 and hope to get down to the range this afternoon. This time I also sorted the brass to be sure that only LC is used. The last batch had a few different headstamps.

I wish someone could give me step my step video instructions for that lee factory crimp die.... Half the time I don't think it's done anything at all lol....
