Hornady One Shot with DynaGlide Plus is a revolutionary formula developed to prevent firearm malfunctions caused by a buildup of lubricants and grime. The unique DynaGlide Plus formula cleans the actions of firearms and leaves a micro-thin layer of dry lubricant. Because One Shot is a dry, non-tacky lube, it smoothes actions and eliminates mechanical fouling due to powder and dirt adhering to the lubricant.
