Bulk 45 ACP Ammo

45 ACP ammo loaded with a jacketed hollow point (JHP) bullet. These rounds are specifically engineered to inflict the maximum amount of damage with a target. These rounds expand when they make contact with a target, allowing for optimum penetration and lethality. Due to standard pressure .45 ACP rounds being inherently subsonic when fired from handguns and submachine guns, it’s a useful caliber for suppressed weapons to eliminate the sonic boom. With our large online selection you can find many variations of .45 ACP ammo here at Gunslinger! The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt’s M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge.
