The Xtreme Defender is based on the Xtreme Penetrator product line. The XD ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth up to 18 inches with a permanent wound cavity (PWC), no other expanding hollow point comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, expansion is achieved despite being shot through barriers. The solid copper body ensures that wallboard, sheet metal, and automotive glass will have no effect on the Permanent Wound Channel. Nickel-plated brass casings, the nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel-plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.
