Whether you punch paper, shoot steel, or use your handgun for hunting, we ensure you have the finest accuracy, consistency, and overall quality. We utilize Nosler® Sporting Handgun™ bullets for their Alloy Jacket. Their tapered jacket is built for maximum accuracy and enhances game-taking ability. The 2 Form-Fitted Pure Lead Core Allows for reliable expansion and maximum accuracy across a broad velocity range.

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.
