The Vital-Shok Trophy Bonded 10mm Auto is a full-power load that takes complete advantage of the caliber's true capability. While most 10mm loads are watered down to produce ballistics similar to those of the 40 S&W, this cartridge offers the muscle needed for both big game hunting and personal protection. The Trophy Bonded Jacketed Soft Point bullet design makes the 10mm Auto load even more effective. Based on Federal's Trophy Bonded Bear Claw rifle bullet, its heavy jacket features a formed inner profile that pre-programs and controls expansion to ensure deep penetration.
