Underwood Ammo Xtreme Defender rounds redefine personal defense with cutting-edge projectile technology. Built on the Xtreme Defense Fluid Transfer Monolithic (FTM) platform, the solid copper EXD projectile features optimized flute geometry, weight and velocity to achieve deep, controlled penetration up to 18 inches while creating a massive Permanent Wound Cavity (PWC). No expanding hollow point comes close to matching this devastating wound channel. Unlike traditional hollow points, the non-expanding solid copper design ensures consistent performance through barriers like wallboard, sheet metal and automotive glass without compromising effectiveness. Nickel-plated brass casings provide enhanced feeding, corrosion resistance and ease of clean-up during reloading. Unlike traditional brass, they resist tarnishing when exposed to moisture, leather or other materials. Underwood Ammo also incorporates flash-suppressed powder to preserve night vision in low-light situations. Rigorously tested with real firearms in real-world conditions, this high-performance ammunition delivers unmatched reliability and stopping power when you need it most.
