About 45-70 Ammo

45-70 ammo, also known as .45-70 Government ammunition, is one of America’s most iconic rifle cartridges, with a legacy stretching back over 150 years.

Introduced in 1873 by the U.S. Army in partnership with the Springfield Armory, the .45-70 was designed as a black powder cartridge for use in the Springfield Model 1873 “Trapdoor” rifle.

Its name comes from the original loading: a .45 caliber bullet over 70 grains of black powder.

Initially created for military use, the 45-70 Government cartridge quickly earned a reputation for exceptional stopping power, making it ideal for frontier use, buffalo hunting, and big-game pursuits across North America.

Hunters, lawmen, and explorers favored the cartridge for its ability to take down large and dangerous game with authority, including bison, moose, bear, and elk.

As smokeless powder technology advanced, so did .45-70 ammo, which was modernized to deliver even better velocity, flatter trajectories, and improved accuracy.

Today, 45-70 ammunition is available in a wide variety of bullet types and loads, from traditional lead flat-nose rounds for lever-action rifles to high-performance jacketed hollow points and monolithic bullets for modern rifles and big game hunting.

The 45-70 Government has had a profound impact on the shooting sports community. It remains beloved by lever-action enthusiasts, cowboy action shooters, and big-game hunters alike.

The cartridge is also a favorite among collectors and historical firearms fans who admire its rich American heritage.

Modern 45-70 ammo is manufactured by top brands like Hornady, Federal, Winchester, Remington, and Buffalo Bore, with offerings that span hunting, target shooting, and cowboy action applications.

Its enduring popularity proves that this old-school powerhouse still has a firm place in the modern shooting world.

Whether you’re chasing whitetail in thick brush, taking on Alaska’s biggest game, or ringing steel at the range, .45-70 ammunition delivers time-tested power and performance that generations of shooters have trusted.
