I'm a bit late to the show here (not a big forum guy) but thought I'd mention that I've been doing the same thing for about 5 years now. Like 470evans I had severe leading in my Paradox after 2 rounds per barrel and accuracy went to hell. I tried Alox, 50/50, and Rooster Jacket all with no success. I decided to try powder coating them and it works like a champ. I have no idea how Sherman and Ross get theirs to shoot with conventional lube but they obviously have more talent than I do. Another nice thing about the PC is it doesn't pick up any dirt.
