Features

Underwood Ammunition leverages state-of-the-art testing equipment to ensure their high-performance rounds meet real-world demands. Field-tested with popular firearms that customers are most likely to own, Underwood guarantees 100% satisfaction with their products. If any performance issues arise, they stand firmly behind their ammunition. This new production ammunition is non-corrosive and features boxer-primed, reloadable brass cases. It's designed to deliver exceptional performance with the Lehigh Xtreme Penetrator bullet. This bullet boasts a progressive nose geometry that ensures deep, straight penetration and creates a permanent wound cavity significantly larger than that of most expanding bullets. The Xtreme Penetrator's solid copper construction and innovative design make it highly effective at overcoming barriers. The radial flutes in the bullet's nose force hydraulic energy inward, then accelerate it outward, creating high-pressure spikes that damage surrounding tissue much like sticking your thumb over a garden hose. This results in a permanent wound cavity that is two to four times larger than what a flat or ball nose bullet produces and often exceeds the size of traditional expanding bullets. With its ability to penetrate hard surfaces without deformation or fragmentation, the Xtreme Penetrator creates a massive wound channel, making it an outstanding choice for self-defense and hunting.
