I don't Moly coat bullets. Maybe I am not qualified to comment but in my mind, Moly coating reduces friction in the barrel. It is not a lube intended to reduce leading in a barrel which is what lube does in both pistols and rifles shooting lead bullets at the high end of the velocity scale. Moly, applied to copper jacketed bullets. works but is difficult to clean whereas if you powder coat a bullet it serves as both a lube that also reduces/eliminates leading on cast bullets. I commented on this in hopes more experienced folks can correct my errant statements.
