Derived from the .50-60-400 Joslyn, the cartridge was developed after the unsatisfactory results of the .58 rimfire cartridge for the Springfield Model 1865 Trapdoor Rifle.
The .50-70 Government cartridge became the official cartridge of the US military until replaced by the .45-70 Government in 1873. The .50-70 cartridge had a pressure limit of 22,500 PSI.
The official designation of this cartridge at the time of introduction was “US Center-fire Metallic Cartridge”, and the commercial designation .50-70-450, standing for :
- caliber .50
- powder charge 70 grains (4.5 g) black powder
- bullet weight 450 grains (29 g)
Ammunition with a black powder charge is currently available commercially from Buffalo Bore. Reloaders have experimented with a variety of bullet weights from 425 to 600 grains (39 g) in weight. Additionally, the US Navy contracted with Remington to produce several thousand Rolling Block carbines chambered for a reduced load version of this cartridge which was officially produced for use only in carbines. This reduced load cartridge used a shortened .50-70 with a 430-grain (28 g) bullet and 45 grains (2.9 g) of black powder.
The US Navy also purchased Remington Rolling Block rifleschambered for the full size .50-70 cartridge. The US Army also ordered both Rolling Block rifles and carbines in caliber 50-70 and also made some Rolling Blocks at their Springfield Armory facility in this caliber. The US Army also had a large supply of percussion fired Sharps carbines at the close of the Civil War and had the Sharps Rifle company convert about 31,000 of those to caliber 50-70 for cavalry use. Meanwhile, the Army, which had exited the Civil War with an inventory of almost a million percussion fired muzzle loaders converted Springfield Model 1863 and Model 1864 muskets to metallic cartridge ammunition using the Allin conversion (trapdoor) method, as well as cadet rifles. The first of the 50-70 conversions was the Springfield Model 1866. Newer improved versions were made and used by the Army through 1873. After 1873 with the advent of the 45-70 cartridge, the Army declared the .50-70 to be surplus and while some rifles in .50-70 were issued to Indian Scouts, the bulk were simply sold off as surplus. In the US Navy however, the 50-70 cartridge and the guns associated with it remained in Navy use until the late 1880s.
Buffalo Bill Cody used a Springfield Model 1866 in caliber .50-70 while hunting buffalo to feed the track workers of the Kansas Pacific Railroad (later Union Pacific Eastern Division). General G. A. Custer was known to have and use a sporterized Rolling Block in caliber 50-70 and was believed to have it with him at the Battle of the Little Big Horn.
As Army General Sheridan had embarked on a plan to eliminate the bison during the course of the American Indian Wars, the 50-70 rifles were also issued, or purchased, by buffalo hunters for use in eliminating the vast Bison herds. Sharps began manufacturing sporterized rifles in 50-70 (and later 50-90, 50-110, etc.) and with improved sights for longer range shots for use by the buffalo hunters.
In 1867 the .50-70 cartridge in US Army Model of 1866 Springfield rifles played a pivotal role in holding off an attacking force of 300-1000 Lakota Sioux Indians during the Wagon Box Fight.
Modern made functional replicas of caliber .50-70 historical rifles have been imported into the US by such firms as Davide Pedersoli and A. Uberti, Srl. (a Beretta subsidiary). The caliber of .50-70 still enjoys some use and popularity from sportsmen and cowboy action shooters.
