Underwood Ammo 638 Xtreme Defense 380ACP 68gr Solid Monolithic 20 Per Box/10 Case,Centerfire Handgun Rounds

Overview

Underwood Ammo Xtreme Defense .380 ACP ammunition is engineered for personal defense and law enforcement applications, featuring a 68 grain solid monolithic copper projectile. Designed with radial nose flutes and an optimized profile, the CNC-machined bullet forces hydraulic energy inward to create a permanent wound cavity significantly larger than traditional expanding hollow points while achieving a penetration depth up to 18 inches through common barriers like wallboard, sheet metal, and automotive glass. This lead-free ammunition delivers a muzzle velocity of 1300 fps and a muzzle energy of 255 ft-lbs, loaded with flash-suppressed powder to preserve night vision and reduced recoil for real-world firearms. Each box contains 20 rounds housed in boxer-primed, reloadable nickel-plated brass cases that offer improved feeding, enhanced corrosion resistance, and simplified cleanup.
