Underwood 475 Linebaugh 300gr - Xtreme Penetrator 20rd 10bx/cs

The Underwood 475 Linebaugh 300gr Xtreme Penetrator represents purpose-built ammunition engineered for maximum stopping power and deep penetration in the most demanding tactical and hunting scenarios. Chambered in the potent 475 Linebaugh cartridge, this round delivers the terminal performance demanded by law enforcement, military personnel, and serious hunters who require uncompromising reliability and energy transfer. The 20-round box format ensures adequate supply for training cycles, qualification courses, and field operations while maintaining Underwood's reputation for consistency and quality control.

Loaded to 1600 feet per second, the 300-grain projectile generates substantial kinetic energy while maintaining velocity stability across varied barrel lengths and environmental conditions. Underwood's Xtreme Penetrator design prioritizes deep, straight-line penetration through intermediate barriers—bone, heavy clothing, and vehicle glass—without premature expansion or bullet fragmentation that reduces effectiveness. The heavier 300-grain bullet weight in the 475 Linebaugh caliber creates a high sectional density, enabling consistent performance through barriers while delivering controlled expansion that maximizes tissue damage and rapid incapacitation for defensive applications.

This ammunition is purpose-designed for single-action revolvers and custom firearms chambered in 475 Linebaugh—a cartridge favored by backcountry professionals, armed civilians in remote regions, and competitive shooters pursuing handgun hunting. The 10-box case quantity (200 rounds total) suits both personal stockpiling and small-team deployment, offering economies of scale for serious practitioners. Proper storage in a cool, dry environment preserves the integrity of Underwood's brass casings and powder charge, ensuring shot-to-shot consistency and reliable ignition across multiple firing cycles and environmental extremes.
