Why Nickel-Plated Brass?

Underwood selected nickel-plated brass casings for superior performance. The nickel plating enhances feeding reliability across all firearm actions, provides exceptional corrosion resistance compared to traditional brass, and resists tarnishing during storage or contact with leather and moisture. Reloaders also appreciate the easier cleanup.

Low-Light Readiness

All Underwood ammunition uses flash-suppressed powder formulations. If you must defend yourself in low-light conditions, you'll maintain your night vision and situational awareness—a critical advantage in defensive encounters.

Whether you're carrying for personal protection or seeking a proven hunting round, this ammunition delivers the performance you need when it matters most.
