The Underwood Ammo .45 Colt 250-grain full metal jacket round delivers proven performance for hunters and shooters who value a subsonic handgun cartridge. This is new production ammunition built on nickel-plated brass cases that are boxer-primed and reloadable, making it a practical choice for shooters who reload. Each round is loaded to 960 feet per second, keeping velocity below the sound barrier—ideal if you're running a suppressor on your .45 Colt revolver or pistol. The 250-grain copper-lead bullet generates 512 foot-pounds of muzzle energy, offering the terminal performance you need for hunting medium game and self-defense applications.
What sets this round apart is its thoughtful engineering for suppressors. The subsonic velocity and full metal jacket construction work together to deliver consistent, reliable performance downrange while keeping noise signature low. The nickel-plated brass case resists corrosion and handles repeated handling and reloading cycles without degradation. Whether you're working up loads or grabbing factory ammo for a hunting trip, the bright cases are easy to spot on the bench or in the field.
Underwood Ammo has built a reputation among handgun hunters and precision shooters for attention to detail, and this .45 Colt load reflects that standard. The ammunition is non-corrosive and manufactured to consistent pressures, so you get uniform ballistics shot to shot. Comes in boxes of 50 rounds, with bulk packaging available in cases of 10 boxes for shooters who move volume.
