The Underwood 10mm Auto 180gr JHP - Bonded ammunition delivers purpose-built stopping power for defensive and duty applications where reliability and terminal performance are non-negotiable. Designed for shooters who demand consistent, predictable results in high-stakes environments, this bonded hollow-point round bridges the gap between the ballistic efficiency of 9mm and the raw power of larger calibers. Law enforcement and civilian users alike trust bonded projectiles for their proven barrier-blind performance and controlled expansion characteristics that minimize over-penetration risk in populated areas.
The 180-grain jacketed hollow-point bullet features a bonded construction, where the copper jacket is molecularly fused to the lead core—a design that ensures the projectile remains intact through barriers and clothing while delivering maximum energy transfer at the target. Propelled at 1,300 feet per second, this round generates 676 foot-pounds of muzzle energy, providing the velocity needed for consistent expansion without sacrificing accuracy or control. The nickel-plated brass casing resists corrosion, simplifies case sorting for reloaders, and enhances feeding reliability in duty weapons that see frequent cycling and variable storage conditions.
This ammunition excels in modern 10mm platforms—from Glock 20/21 and 1911 variants to lever-action rifles and specialized tactical carbines that chamber the cartridge. The 20-round-per-box format allows shooters to stock duty loads and practice ammunition efficiently, while the 10-box case pack (200 rounds) supports range training schedules and team qualification protocols. Whether you're outfitting a defensive handgun, validating duty loads, or maintaining proficiency with a service weapon, Underwood's consistent QC and bonded construction deliver the terminal ballistics professionals expect.
