One Shot Case Lube is the most popular reloading cartridge and tool lubricant in the market, because; Case Lube is a dry film "Boundary" lubricant that is non-hazardous, does not contaminate powders or primers, and the "DynaGlide"(TM) technology exceeds US Military & NATO load carrying capacity requirements by 6 times. Precision shooters appreciate One Shot Case Lube's clean, non-sticky, quick and easy application when loading large volumes of rounds at a time. The flexible all-purpose dry film lubricant use on the other reloading tools is a major bonus.
