I tried something a few days ago and it worked VERY good. Now I'm told not to put soft lube in a 45 Colt.......What I did was, I used the soft lube I use in my 45-70 black powder rifle.... It came out good, NO leading at all, only I did see a little more smoke that came out of it...........Question..."Why can I not use soft lube in a 45 Colt"???? beng
