Underwood Ammo 45 Long Colt, 135gr. Extreme Defender, 20rd Box

The Xtreme Defender is based on the popular 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) that is just simply enormous; no other expanding hollowpoint 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.
