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.

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.

While taking advantage of their state-of-the-art testing equipment, this high-performance ammunition is field tested using popular, real firearms that their customers are most likely to own out in the real world with all the elements you would experience.

As with all of Underwood Ammo rounds, they utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

The primary advantages of the Platinum Edition coating are as follows:

Improved Corrosion Resistance of the Copper: There will not be any oxidation (brown spots) or darkening of the copper projectile over time or extended storage. In aggressive applications such as wet, humid and even salt water, the coating will protect the copper from oxidation or verdigris. This is very beneficial for self-defense ammo that is often purchased and stored for use for extended periods of time.
Improved Lubricity & Enhanced Feeding: The finish provides excellent dry-film lubrication that helps with feeding in all actions of firearms. The coating is very forgiving on modified guns since it reduces the friction of the projectile against the feed ramp as well as the chamber entrance.
Reduced Barrel Wear: The coating reduces barrel wear over a standard monolithic projectile.
