Well, I just wanted to report, I finally used the Lee Factory Crimp Die and I have to say, it is the heat. It makes a very nice roll crimp, plus it sizes the case on exit, just make sure it will fit in the chamber of the Blackhawk without issues. I am very happy with the die and it was worth the 20.00 I paid for it. Now I need to get out and test out the 240gr Nosler JHP's I loaded. I have them loaded them up to 23.5gr of H110 for my hunting load I hope! Very economical bullet and should work well on deer/bear and lions if given the chance! Scotty
