History of 45 Long Colt Ammo

The .45 Long Colt (LC), or .45 Colt, has a rich U.S. history. Developed by Samuel Colt in 1872 for the Colt Single Action Army revolver, it features a .454-inch bullet in a 1.285-inch case. Originally loaded with black powder and a 255-grain lead bullet, it reached up to 900 fps. Modern loads, known for accuracy and stopping power, typically have 400 foot-pounds of muzzle energy and a velocity of 860 fps.

Produced by Colt Firearms and Union Metallic Cartridge Company for the Colt Single Action Army, the .45 LC became the official U.S. Army handgun and ammunition in 1873. Known as “the gun that won the west,” it remained popular with civilians, transitioning from black powder to smokeless powder. Hunters, sport shooters, Cowboy Action Shooting enthusiasts, and handloaders appreciate its versatility, with modern loads reaching over 1,000 fps.

    Barely had to clean my rifle after shooting an entire box and had my rifle dialed in very quickly as a result of very little shot variation using this ammo.

  • spymyeyes said:

    This is without a doubt the CLEANEST ammo I have ever bought. The lead nose is painted so zero lead fingers! Every round went bang and cycled perfectly. Keep up the great work!

    love this Hornady 45 Long Colt.

  • OldNavy said:

    This ammunition was dead-on accurate at 45 yards. However, the THX tip added a small amount of additional length such that every round would jam in attempting to cycle into the chamber of my Henry .45LongColt lever-action rifle. Shorter, hollow point ammunition had no problems.
