There's no reason to even mess with moly unless you have an absolute need to shoot 100 or more rounds in a row without fouling the barrel with copper. Its a whole lot of screwing around for very little benefit, worse still, the stuff will wreck your rifle bore if you live in a humid environment and don't scrub the stuff out carefully as soon as you are done shooting.
I'm curious how you think this stuff will wreck your barrel in a humid environment. I'm not for or against the use of moly as a bullet coating, but I am an Aircraft Electrical/Environmental Technician for the Air Force, and we use moly on every plane in our inventory for it properties as a lubricant and the fact that it is not corrosive.
