RE: moly damage to your barrel
Once Moly gets inbedded in barrels/bearing/whereever its used, it seems impossible to get all out. Which is a good thing if you plan on shooting them only in that gun. According to machinist and all who use it for 30 years, it can't eat barrels or metal, but is sort of hydrscopic (can attract moisture). So instead of using it as some say, by shooting moly and never cleaning it out or oiling, I would clean it out with Kroil and oil your barrel after use. Some snipers for cities say they like it cause your barrel will have good cold shot performance if you don't clean out and use a bore snake after using. Hope it helps.
