Ran out of Lee Liquid Alox, so I tried some JPW on my .45 acp cast bullets. Tumble lubed them with straight JPW. I ran about 100 rounds through my FN 45 yesterday. I had some lead streaks in the barrel, but copper Choreboy and some scrubbing took care of that. I run these Lyman mold bullets without sizing. I know the general consensus here is that size of bullet is more important then lube used. Any of you lube with JPW? Are you cutting it with mineral spirits or adding Alox?
