X-Treme's process starts with a lead bullet that is extruded into wire. The lead wire is swaged into a core, then copper plated and re-struck once more. Though not common in the industry, this restrike process produces a more uniform bullet, exacting a precise diameter and a smoother finish for better shooting and aesthetics. X-Treme Bullets are proudly made out of the finest materials available in the United States in order to ensure performance delivered down range with each and every shot.
