A friend used moly bullets in his competition AR-15 for cross-course highpower, and shot over 2,000 rounds without cleaning anything. He usually shot a 787/800. If you use moly, clean after each session with 4-5 strokes of bristle brush coated with whatever solvent, and 4-5 patches of same solvent, like Shooter's Choice or Hoppe's 9. Run a couple of dry patches through, and put it up. When the bore is due for a more complete cleaning, get after it with BoreTech copper solvent until it's clean, then any solvent, again such as BoreTech carbon solvent, BoreTech Eliminator, or Hoppe's. I also sometimes use Boron but I have not seen anyone do the same as my friend did with his high-power competition rifle, but using boron. Some rifles have a predictable zero on the first shot after cleaning, when doing as mentioned above. That's the advantage to me, when hunting. But if you check cold-bore zero, you know what's going to happen no matter whether or with what you coat your bullets. After a more thorough cleaning regimen, you will have to wait 7-12 shots for the accuracy to settle down. Last one I cleaned, the first 6 shots were all over creation, and the next six were in 0.5". Just noted 'stool' post, and agree.
