I have no great insight regarding moly coated bullets aside from some personal experience. I did some load testing recently with wet coated moly bullets namely 75 gr A-max .224 in my .223.
Just a couple points:
Cleaning is messier. I use boretec extreme and it works well. You can expect a good deal of black sludge and will need extra rags over naked bullet shooting. Clean you chamber as even with a bore guide, stuff will leak into the chamber.
It is somewhat harder to see copper fouling. The rod gets coated with the sludge so wipe after each patch change. That is pretty much it, I will still use moly coated bullets but you need to develop loads separately for them.
