Please forgive me for asking stupid questions, but I'm kinda new at doing things correctly. Years ago I cast a number of .30 caliber rifle bullets, and (as I didn't know about powder coating) tumble lubed them with Lee Liquid Alox, and gas-checked them. Now that I've tried powder coating some pistol bullets I like that a lot better and would like to powder coat the rifle bullets. Obviously the powder will not work over the LLA, so what's the best way to clean off the old lube. I have mineral spirits and lacquer thinner, but don't want to leave a residue.
Thanks for any suggestions.
