Underwood 10mm Auto 155gr - Xtp Jhp 20rd 10bx/cs

Underwood 10mm Auto 155gr XTP JHP ammunition delivers reliable, powerful performance for defense-oriented shooters and law enforcement personnel who demand consistent terminal ballistics. This factory-loaded round pairs a 155-grain Hornady XTP hollow-point bullet with Underwood's quality brass and propellant, making it a trusted choice for those who rely on their sidearms in critical situations. The 10mm platform has proven itself across tactical and duty applications, and this load optimizes that cartridge's natural velocity and energy delivery characteristics.

The 155-grain XTP hollow-point design expands reliably across typical barrier-free engagement distances, creating a larger wound channel and controlled penetration depth—critical factors in defensive scenarios. Hornady's XTP bullet construction uses a copper jacket mechanically bonded to a lead core, resisting fragmentation and ensuring predictable expansion at the velocities this 10mm load generates. Underwood's brass cases are new, unprimed stock reloadable by handloaders seeking to maximize ammunition cost-effectiveness, while the consistent powder charges and primer selection support shot-to-shot velocity uniformity essential for accuracy work and combat accuracy training.

Tactical professionals, duty shooters, and serious sport competitors running 10mm platforms—particularly single-stack and compact models—will find this load suitable for duty carry, duty qualification, and defensive practice. Law enforcement agencies and private security personnel training with the 10mm benefit from ammunition that mirrors their duty round's ballistic profile. The 20 rounds per box format allows flexible purchasing in bulk (10 boxes per case), accommodating both individual shooters stocking defensive reserves and agencies managing training inventories. Compatibility extends across all modern 10mm auto platforms, from compact carry guns to full-size service pistols.
