I've been using moly for a long time. I like it a lot and my bore scope tells me I've never had a problem. You need to start with a completely clean barrel after you are satisfied that the barrel is broken in. Don't break in the barrel with moly. Now, Midway use to sell a really thick liquid designed to condition a barrel for moly. I still have a little but am about to run out.. You put it on a patch and run a couple thru the bore, back and forth, until the barrel is fully coated. The last time I checked with Midway, they had stopped carrying that product and I haven't been able to locate any anywhere. It worked really well... While searching around trying to find that product, I found a product that is made by Lyman (usually in the Moly coating section of a catalog) called, "Super Moly Bore Cream" ...I bought a jar but I haven't tried it yet.. Its made specifically for coating the bore before shooting with moly coated bullets. I believe Midsouth has it but I did not check before answering your question here,.... That's what I will use when the liquid from Midway runs out,...You might consider that...I believe it will do the job just as well...
