About
The .45-70 Government Ammo was designed and developed in 1873. The cartridge was created to replace the stopgap .50-70 Government Ammo. The .45-70 Government Ammo has the minimum accuracy of 4-inch drop at 100 yards, but the slow and heavy bullet in longer ranges would have a rainbow trajectory. Still, skilled shooters can easily hit targets with ease using the .45-70 Government Ammo. This cartridge was even used in several Gatling gun models, especially on US Navy warships in the 1880s and 1890s. The .45-70 Government Ammo is s super hit amongst the sportsmen, and that's the main reason this bullet is still alive today. The overall length of the .45-70 Government Ammo is 53.5mm, while the bullet diameter measures 11.6mm. One variant of the .45-70 Government Ammo is loaded with 300-grain that can travel at a velocity of 2,275 feet per second and produce an energy level of 3,449 ft.lbf.Â
Manufacturer
To fill out the gap left by the 50.70 Government Ammo, the US Army's Springfield Armory designed and developed the .45-70 Government Ammo.
Uses
The traditional 405-grain variant of the .45-70 Government ammo can take down any North American big game species within its effective range. Thanks to its low velocity, the .45-70 Government Ammo doesn't destroy the edible meat on the delicate game like deer. The .45-70 Government Ammo holds the potential of taking down the big five African game in the range of 1,000 yards.Â
The .50-90 Sharps rifle cartridge is a black-powder cartridge that was introduced by Sharps Rifle Manufacturing Company in 1872 as a buffalo (American bison) hunting round. Like other large black-powder rounds, it incorporates a heavy bullet and a large powder volume, leading to high muzzle energies. The standard factory loads, produced and sold by the Sharps Rifle Manufacturing Company and the Sharps Rifle Company were .50/100/425 (.50 caliber/100 grains black powder/425 grain grease grooved bullet) and .50/100/473 with a paper patched bullet. Factory loads manufactured by any of the Sharps companies were mostly hand-loaded which made them expensive to produce. This naturally invited competition. Winchester offered the cartridge loaded .50/90/473 with paper patched bullets which may be how the cartridge came to be commonly known as the .50-90. The .50-90 Sharps is similar to the .50-100 Sharps and .50-110 Sharps cartridges. All three use the same 2.5-inch (64 mm) case, the latter two being loaded with more grains of black powder. All rifles made for the .50-90 Sharps should be able to use the .50-110 and .50-100 cartridges due to the case dimensions being nearly identical.
Bullet diameter was typically 0.512 inches (13.0 mm) diameter. Bullets weighed from 335 to 700 grains (21.7 to 45.4 g). Historical loads using black powder have muzzle energy in the 1,630 to 1,985 foot-pounds force (2,210 to 2,691 J) range, while modern loads using smokeless powder give 2,561 to 2,989 foot-pounds force (3,472 to 4,053 J) of energy.
