Underwood Ammo XTP Jacketed Hollow Point Handgun Ammunition 45 Colt (+P) 250gr JHP 1400 fps 20/ct

Underwood Ammo XTP Jacketed Hollow Point ammunition for .45 Colt (+P) delivers serious stopping power built on proven terminal performance. This is heavy hitter defensive and hunting ammo: 250-grain XTP bullets loaded to 1400 feet per second, generating 1088 foot-pounds of muzzle energy. The XTP (eXtreme Terminal Performance) design is engineered to expand on impact while maintaining structural integrity—exactly what you want when it counts. Each box contains 20 rounds of new production ammo loaded into non-corrosive boxer-primed brass cases that you can reload.

Built for shooters who demand reliability from their .45 Colt (+P) handloads, this round trades volume for velocity and energy. The 250-grain projectile carries enough mass and energy to be effective on medium-sized game and is respected for personal defense applications. Supersonic performance means consistent ballistics and reliable function across a wide range of firearms. The ammunition is suppressor-safe, making it a smart choice if you're running a can on a suitable .45 Colt revolver or pistol.

Underwood's focus on quality control and consistent powder charges means you can count on shot-to-shot reliability. The XTP projectile's sectional density (0.175) and ballistic coefficient (G1 0.146) favor penetration over flat trajectory, appropriate for the caliber's typical engagement distances. If you're looking to maximize terminal performance from your .45 Colt (+P) handgun, whether for hunting, defense, or serious target work, this is purpose-built ammunition that won't disappoint.
