Underwood 10mm Auto 150gr - Jhp 20rd 10bx/cs

Underwood 10mm Auto 150gr JHP ammunition delivers reliable stopping power for defensive shooters, competitive marksmen, and law enforcement professionals who demand consistent performance. This 20-round-per-box offering represents a tested platform for self-defense and duty carry, where shot placement and terminal ballistics matter. Built by Underwood Ammo—a brand trusted across the tactical community—each round is engineered to meet exacting standards for pressure, velocity, and expansion in real-world scenarios.

The 150-grain jacketed hollow point (JHP) bullet profile is optimized for the 10mm Auto platform, balancing velocity retention with controlled expansion at typical engagement distances. This weight class reduces felt recoil compared to heavier loads while maintaining energy transfer necessary for barrier penetration and intermediate targets. The hollow point design initiates expansion upon impact, creating a larger wound channel while minimizing over-penetration in urban environments—a critical consideration for duty carry where bystander safety is paramount.

This ammunition pairs seamlessly with full-size and compact 10mm Auto pistols, including models from Glock, FN, S&W, and Springfield Armory platforms. Law enforcement agencies transitioning to 10mm, private security contractors, and civilian shooters maintaining proficiency with modern defensive calibers will find this load consistent across the 20-round box and across production runs. Ten boxes per case (200 rounds total) support range training, qualification cycles, and duty stockpiling without sacrificing batch-to-batch reliability.
