Underwood Ammo 10mm 150gr JHP - 20 Round Box Premium Defense Ammo

The Underwood Ammo 10mm 150gr Jacketed Hollow Point delivers maximum stopping power for serious defensive applications. This premium ammunition combines consistent performance with devastating terminal ballistics that standard factory loads simply cannot match.

What Makes This Different

Underwood's 10mm loads generate significantly higher velocities than typical factory ammunition, pushing the 150-grain JHP to approximately 1,300 fps from a 4-inch barrel. The nickel-plated brass cases provide superior corrosion resistance and smooth feeding compared to standard brass. Each cartridge undergoes rigorous quality control testing to ensure consistent powder charges and precise bullet seating.
