Underwood

Underwood Ammo™ XTP rounds are notable for their power and accuracy. We utilize Hornady eXtreme Terminal Performance (XTP) bullets which are designed for deep terminal penetration, great accuracy and controlled expansion. We combine Hornady unparalleled XTP bullets with our own carefully formulated design which results in one lethal round.<

Nickel-plated brass casings, our 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.

As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

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