Underwood Ammo Xtreme Defense Features The Underwood Ammo Xtreme Defense round in .32 ACP uses a solid monolithic copper bullet engineered from the Xtreme Penetrator platform with an optimized nose flute designed to maximize penetration depth without sacrificing expansion. Independent testing shows this bullet achieving penetration up to 18 inches while generating a permanent wound cavity over 100 percent larger than typical expanding hollow points. Because the bullet body is solid copper rather than a jacketed lead core barriers like wallboard sheet metal and automotive glass have little effect on the wound channel it creates. Rated +P and driven to 1050 fps this load is built specifically for personal defense applications where reliable terminal performance matters most. Nickel plated brass casings give this round smoother feeding across a wide range of pistol actions along with stronger resistance to corrosion than standard brass cases. The plating keeps cases from tarnishing in storage or when exposed to leather moisture or other metals commonly found in a carry holster or range bag. Each box contains 20 rounds giving shooters a practical supply for practice and carry rotation alike. The result is a dependable barrier-defeating defensive round for shooters who carry a .32 ACP platform and want performance beyond what standard pressure loads provide.
