The .50-90 Sharps (13x64mmR), also known as the .50-2 1 ⁄ 2" Sharps, is a black-powder rifle 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 Sharps rifles supplied to anti-slavery factions earned the name "Beecher's Bibles", after the famed abolitionist Henry Ward Beecher. The Model 1874 Sharps (this model had been in production since 1871) was a particularly popular rifle that led to the introduction of several derivatives in quick succession.
The .50-140 was created for big game hunting, and was the most powerful of the Sharps Bison cartridges. [5] However, it was introduced about the time of the end of the great Bison herds. [6] An obsolete round, ammunition is not produced by any major manufacturer although reloading components and brass can be acquired or home-built.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The 5-inch (127 mm)/54-caliber (Mk 45) lightweight gun is a U.S. naval artillery gun mount consisting of a 5 in (127 mm) L54 Mark 19 gun on the Mark 45 mount. [1] It was designed and built by United Defense , a company later acquired by BAE Systems Land & Armaments , which continued manufacture.
Many such cartridges were designated by a three-number system (e.g., 45–120–3 1 ⁄ 4 Sharps: 45-caliber bore, 120 grains of (black) powder, 3 1 ⁄ 4-inch long case). Other times, a similar three-number system indicated bore (caliber), charge (grains), and bullet weight (grains). The 45-70-500 Government is an example.
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 rifle. The .50-70 Government cartridge used the Benét internal center-fire primer design and became the official cartridge of the U.S. military in 1866 until being replaced by the .45-70 Government in 1873.
While various bullet weights were used, a typical load for the .45-90 was a powder charge 90 grains (5.8 g) gunpowder (black powder) with a bullet weighing 400 grains (26 g). Such a load would have had a muzzle velocity of around 1,300 ft/s (400 m/s).
