Cartridge Hall of Fame: 45-70 Government Ammunition | MidwayUSA
The .45-70 Government cartridge, inducted into MidwayUSA's Cartridge Hall of Fame, was adopted by the U.S. Army in 1873 for the Springfield Model 1873 rifle. Originally a medium-power cartridge with 70 grains of black powder and a .45 caliber bullet, it's known for its straight-wall, rimmed design. Today, it remains popular for large game hunting and cowboy action shooting, with bullet weights ranging from 300 to 550 grains.
