This Hornady .357 Magnum Custom Pistol ammunition is loaded with a 158 grain Hornady XTP (eXtreme Terminal Performance) bullet. The XTP is a high-quality hollow-point projectile designed for optimal performance in hunting, self-defense, law enforcement and competition shooting applications. It demonstrates extreme accuracy and enhanced stopping power by initiating controlled and balanced expansion even at low velocities, presenting an advantage over plated bullets. Each XTP Bullet has a swagged core and drawn copper jacket to ensure uniform expansion and in-flight stability. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
