.45 Automatic Ammo

show category description


45 ACP, or 45 automatic colt pistol, might be the most effective combat ammunition ever made. Known for accuracy and stopping power, John Browning developed 45 auto rounds in 1904 for the U.S. Cavalry before the caliber was adopted for the Colt 1911. Many military and law enforcement units still rely on 45 ACP ammo today to protect communities and nations all over the world.

.45 ACP Ammo on a table

Mostly a low velocity round, that doesn’t mean .45 ACP ammo doesn’t pack a punch. In fact, shooters have enjoyed the benefits of .45 auto as a self-defense round for more than a century now.

If you’re looking for training rounds, you’re likely to look to full metal jacket (FMJ), total metal jacket (TMJ) or metal case (MC) rounds for plinking at the range. If you’re looking for a more sophisticated bullet that will offer expansion and increased self-defense performance look to a jacketed hollow point (JHP) projectile. Federal’s Hydra-Shok is among the best sellers in the AmmoMan.com line-up when it comes to self-defense rounds.

185 grain or 230 grain bullets are considered standard by most 45 ACP pistol shooters. Of course, you can find variants slightly lighter. At 230 grain, expect a muzzle velocity of around 830 feet per second. Lighter rounds at 185 grain will travel faster at just shy of 1,100 feet per second.

While powerful, many shooters claim to feel a different type of recoil with a .45 ACP cartridge than they do with some smaller and faster calibers. Described as less “snappy”, you might compare .45 ammo to a freight train with smaller, faster calibers more like a sprint car.
