They want you to slick up - polish the barrel first, before using moly or pure copper bullets.

Same deal with Amsoil Oil Motor Oil - advised to put 5,000 to 8,000 miles on the engine to break/wear it in before switching to the synthetic - need to break it in first with cheap normal oil, then put in the good stuff and stop wear at that point.

Most standard solvents will not touch moly fouling.

Most barrels, if cleaned back to steel, or if naked bullets are shot, you may need to fire 5 to 15 moly coated bullets to re-coat the bore with moly, before they start shooting perfectly again. Depending on the cartridge's size, it can take .2gr. to 2.0gr. to re-achieve the velocity loss when switching to moly coated bullets. The larger the case, the more powder it takes.
