Underwood Ammo

Underwood Ammo™ standard Jacketed Hollow Point rounds are unrivaled. We use the Nosler® Assured Stopping Power™ (ASP) projectiles, which feature deep skives designed to create a versatile handgun bullet for use in a variety of applications. The deep skives enhance the expansion characteristics of the ASP™ bullet without sacrificing accuracy and reliable feeding. The skives in the jacket mouth create precise reliefs in the jacket, which allow for rapid, consistent, reliable expansion. This reliable expansion assures energy transfer and stopping power while limiting the likelihood of over-penetration.

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.
