The Federal Premium 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. Premium hunting bullets are matched with select powders, primers and brass to create a reliable, hard-hitting hunting cartridge. The Jacketed Soft Point provides consistent expansion in many applications. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.
