Underwood 10mm Auto 200gr - Hard Cast Lead Fn 20rd 10bx/cs

Underwood 10mm Auto 200gr Hard Cast Lead FN ammunition is purpose-built for defensive carry, hunting, and tactical training where deep penetration and reliable barrier performance are non-negotiable. The 10mm platform has earned its reputation among law enforcement and civilian operators as a potent duty round, and Underwood's hard cast formulation delivers the terminal consistency that professionals demand. Each box contains 20 rounds loaded to exacting specifications, making this a trusted choice for shooters who require consistent performance across varied engagement distances and environmental conditions.

The hard cast lead projectile with flat nose geometry is engineered to resist deformation and maintain velocity through intermediate barriers—a critical advantage in real-world defensive scenarios. Loaded to 1250 feet per second with 694 foot-pounds of muzzle energy, this load achieves a ballistic profile that balances controllability with stopping power, particularly effective in full-size and compact 10mm platforms. The nickel-plated brass case ensures reliable feeding, corrosion resistance, and straight extraction, while the robust construction allows for both factory shooting and reloading by experienced handloaders seeking consistent brass stock.

This ammunition performs optimally in modern 10mm pistols—from full-size duty weapons to compact carry platforms—and is equally suited for hunters pursuing medium game where deep, controlled penetration is required. The flat nose design reduces pressure spikes and promotes reliable chambering in single-stack and double-stack designs alike, while the hard cast construction minimizes jacket separation, ensuring consistent performance downrange. The 20-round box configuration fits standard ammunition management protocols, and bulk case purchases (10 boxes per case) accommodate both range training regimens and secure stockpiling for serious defensive shooters.
