YES.... Lee Factory crimp dies ....
I can't believe I don't have one for 45 acp..
I have a lee factory crimp die for every rifle I reload for but none for any handguns I reload for. They are great.
Next stop for me is
http://www.midwayusa.com. I'm going to order lee factory crimp dies for 9mm, 40 and 45 acp.
RE: the R-P brass. I've noticed that also. I've seen some as thin as .007". that's almost half as thick as new starline brass. That kind of stuff makes sorting by brand a good idea.
