The Hornady XTP Mag .45 Caliber 300gr Hollow Point (brand part no. 45235) is a heavyweight component bullet built for reloaders loading the biggest .45-caliber Magnum handguns. Precise serrations divide the jacket into symmetrical sections that strategically weaken it, initiating controlled expansion even at lower velocities, while the gilding metal jacket protects the nose and keeps core density uniform for balanced, stable flight. XTP Mag bullets deliver the same controlled expansion and dependability as the standard XTP line, but are built to withstand the higher pressures and impact velocities generated by full-power Magnum handguns.
