RCBS Sidewinder case tumbler, 2 oz's of their liquid media cleaner, 2 qt's warm water, 2 qt container of de-primed brass, 2 hrs in the machine, rinse and lay flat on towel to dry overnight. Exceptionaly clean, top them off with a Montana Gold jacketed or Laser Cast head and expect a lot of flack at the range about having the "Best looking ammo in town".....Untill someone has some Lapua 338 they want to show off with their new rifle, or some nickel plated .45 Colt they want to "Look Good" at some cowboy match, then the same guy's send it home with me.
