Underwood 10mm Auto 180gr XTP JHP Ammunition /20

Underwood eXtreme Terminal Performance 10mm Auto 180gr XTP JHP Ammunition /20

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.

About the Brand Name
XTP� (eXtreme Terminal Performance) was designed for hunting, self-defense and law enforcement applications, the XTP� bullet demonstrates the kind of accuracy which led many competitive shooters to adopt it. Its reliable performance makes the XTP� the most popular handgun bullet for both target shooters and hunters. It's the stopping power of the XTP� bullet that has truly built its world-class reputation. From the onset, XTP� bullets were specifically designed to expand reliably at a wide range of handgun velocities to deliver deep penetration with every shot.

Features: Precise serrations divide the XTP� into symmetrical sections, strategically weakening the jacket and initiating controlled expansion even at low velocities.

Total uniformity of core density ensures balanced expansion as well as in-flight stability

Expansion is controlled by varying jacket thickness down the length of the XTP�, providing a definite advantage over plated bullets which have a uniform jacket thickness over the entire bullet.

On revolver bullets, the cannelure helps achieve accurate, consistent, crimping. All cannelures are applied before the final forming process to eliminate any distortion to the finished bullet.
