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

Nickel plated casings with their new 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.

Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass. It was claimed that nickel plated brass casings embrittled the brass therefor making it less desirable for reloaders despite the ease of cleanup that nickel plating offers. In addition, ammunition engineers raising concerns of using nickel plating in very hot +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.

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