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.Other References
