XTPA(R)Extreme Terminal Performance Designed for hunting, self-defense and law enforcement applications, the XTPA(R) bullet demonstrates the kind of accuracy that led many competitive shooters to adopt it. Reliable performance makes the XTPA(R) the most popular handgun bullet for both target shooters and hunters. But it&';s the stopping power of the XTPA(R) bullet that has truly built its world-class reputation. From the onset, XTPA(R) bullets were specifically designed to expand reliably at a wide range of handgun velocities to deliver deep penetration with every shot. Description: Controlled Expansion: Precise serrations divide the XTPA(R) into symmetrical sections, strategically weakening the jacket and initiating controlled expansion even at low velocities. No exposed Lead: The gilding metal jacket protects the nose of the bullet, so the hollow cavity functions properly on impact and ensures proper feeding in semi-automatics. Swaged Cored: Total uniformity of core density ensures balanced expansion as well as in-flight stability. Drawn gilding metal jacket: Expansion is controlled by varying jacket thickness down the length of the XTPA(R), providing a definite advantage over plated bullets which have a uniform jacket thickness over the entire bullet. Cannelure: On revolver bullets, the cannelure helps achieve accurate, consistent crimping. All cannelures are applied before the final forming process to eliminate any distortion to the finished bullet.
