My brother Lou swears by those lead moly coated black bullets from (ithink) Precision. I'm gonna give them a try in 200gr. round nose and 200gr. LSWC over 4.8gr TiteGroup for use in 1911s.
My question is, if I shoot 50 to 100 rounds of the black bullets and then without cleaning shoot copper jacketed bullets will that make the black stuff nearly impossible to remove with normal cleaning with Hoppes 9? If you have tried the black projectiles what do you think about'em? Good? Bad? Thanks For Your Time VonBarkyBuckBuck |

The moly may blacken the inside of the barrel, but it's not going to hurt it. As it gets hot, the moly is going into any pores in the barrel.
For quite a while now, I've been using Lyman spray moly in a couple of my 1911 barrels. I just started with them well cleaned, and while they get a black appearance after a while, it's still a good clean barrel. In my experience, it makes them a little easier to clean. For what it's worth, I shoot mostly lead, but I'd never give a second thought to shooting a jacketed bullet through it, and have on many occasions. No issues whatsoever. |

I use a ton of them in 40 and 45 as well as plated and of course, FMJ. Make sure that you remove any copper in the barrel before you start using them so it can't scrape off the moly and they'll keep your barrel looking new. They work great in polygonal barrels like Glocks with no issues too. Load them using lead bullet powder levels as the core lead is soft. Stay away from super fast powders like TiteGroup with them as the high temps can burn through the moly. ETA: The pre-coated moly bullets like Precisions don't leave residue in the barrel to blacken them. |
