ABSTRACT:
Metal jacketed or lead alloy bullets are placed in a tumbler or vibratory device and mixed with a selected quantity of steel shot having either the same size or a plurality of different sizes and tungsten disulfide powder. The mixture is tumbled or vibrated for a selected time until the tungsten disulfide is plated to the outside surface of the bullets by the impact of the steel shot upon the bullets. This plating acts as a heat resisting and friction reducing lubricant which preserves the interior of the rifle barrel, reduces copper fouling, permits shooting at normal barrel pressures and faster bullet velocities and improves the accuracy of the shooting.
