Metal jacketed or lead alloy bullets are placed in a tumbler and mixed with a predetermined quantity of steel shot and molybdenum disulphide powder and corn cob grits or other fibrous material. The mixture is tumbled for a predetermined time until the molybdenum disulphide forms a coating adhering to the outside surface under the impact of the steel shot. The fibrous material acts to polish the surface of the bullets. This coating acts as a highly superior heat resisting and friction resisting lubricant which preserves the interior of the rifle barrel and improves the accuracy of the shooting.
