.45-70 Government Ammo

               .45-70 GOVERNMENT AMMO

.45-70 Government Ammo and .45-70 Springfield, was developed at the U.S. Army’s Springfield Armory for use in the Springfield Model 1873, which is known to collectors as the “Trapdoor Springfield.” The new cartridge was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War.

             HISTORY OF .45-70 GOVERNMENT AMMO

The predecessor to the .45-70 was the .50-70-450 cartridge, adopted in 1866 and used until 1873 in a variety of rifles, many of them were percussion rifled muskets converted to trapdoor action breechloaders. The conversion consisted of milling out the rear of the barrel for the trapdoor breechblock, and placing a .50 caliber “liner” barrel inside the .58 caliber barrel. The .50-70 was popular among hunters, as the bullet was larger than the .44 caliber and also hit harder (see terminal ballistics), but the military decided as early as 1866 that a .45 caliber bullet would provide increased range, penetration and accuracy. The .50-70 was nevertheless adopted as a temporary solution until a significantly improved rifle and cartridge could be developed.

The result of the quest for a more accurate, flatter shooting .45 caliber cartridge and firearm was the Springfield trapdoor rifle. Like the .50-70, the .45-70 used a copper center-fire case design. A reduced power loading was also adopted for use in the Trapdoor carbine. This had a 55 grain (3.6 g) powder charge.

Also issued was the .45-70 “Forager” round, which contained a thin wooden bullet filled with birdshot, intended for hunting small game to supplement the soldiers’ rations.This round in effect made the .45-70 rifle into a 49 gauge shotgun.[

The .45-caliber Springfield underwent a number of modifications over the years, the principal one being a strengthened breech starting in 1884. A new, 500 grain (32 g) bullet was adopted in that year for use in the stronger arm. The M1873 and M1884 Springfield rifles were the principal small arms of the U.S. Army until 1893.

The .45-70 round was also used in several Gatling gun models from 1873 until it was superseded by the .30 Army round beginning with the M1893 Gatling gun.Some .45-70 Gatling guns were used on U.S. Navy warships launched in the 1880s and 1890s.

The Navy used the .45-70 caliber in several rifles: the M1873 and M1884 Springfield, the Model 1879 Lee Magazine Navy contract rifle, and the Remington-Lee, the last two being magazine-fed turnbolt repeating rifles. The Marine Corps used the M1873 and M1884 Springfield in .45-70 until 1897, when supplies of the new M1895 Lee Navy rifle in 6mm Lee Navy, adopted two years before by the Navy, were finally made available.

Realizing that single-shot black-powder rifles were rapidly becoming obsolete, the U.S. Army adopted the Norwegian-designed .30 Army caliber as the Springfield Model 1892 in 1893. However, the .45-70 continued in service with the National Guard, Navy, and Marine Corps until 1897. The .45-70 was last used in quantity during the Spanish–American War, and was not completely purged from the inventory until well into the 20th century. Many surplus rifles were given to reservation Indians as subsistence hunting rifles and now carry Indian markings.

.45-70 Government Ammo is still used by the U.S. military today, in the form of the “cartridge, caliber .45, line throwing, M32,” a blank cartridge which is used in a number of models of line throwing guns used by the Navy and Coast Guard. Early models of these line throwing guns were made from modified Trapdoor and Sharps rifles, while later models are built on break-open single-shot rifle actions.
