The center fire cartridge .577 Snider ( 14.7 × 50 mm R ) was a British black powder cartridge. It was developed by Edward Mounier Boxer in the Woolwich Arsenal for the converted English Enfield M1853 muskets and is therefore sometimes referred to as the boxer cartridge. But the name after the weapon has prevailed. The Enfieldgewehre were by milling the chamber and installation of a Tabatièreverschlusses to Snider-Enfield rifles with rear cargo converted. The .577, developed from around 1860 onwards, was one of the first metal cartridges for rifles and was in use until the 20th century.
development
In August 1860, the American Jacob Snider submitted a draft for a rear- loading rifle to the War Office . The original cartridge for the rifle was developed according to the design of the French Clément Pottet and Eugène Schneider. The tube was still made of cardboard . Schneider had his system patented in France in 1858 and in England in 1861. The patent rights of Pottet / Schneider were bought in England from the gunsmith George H. Daw. Snider arranged this sale himself in 1861. Daw had the cartridges manufactured and successfully offered them on the civil market. Daw and Snider initially worked together on the coordination of the rifle and ammunition, until a personal rift ended this cooperation. Snider then approached the ammunition manufacturer Eley Brothers . Due to the possible large order from the military, a lot of money was involved. Eley copied the Daw cartridges and the manufacturing process with minor changes. Daw took legal action against it and obtained an injunction in November 1865. In mid-1866, Boxer developed the cartridge further. The sleeve now consisted of wrapped brass sheet, pasted with paper on the outside. A bottom plug made of pressed paper was located in the 10 mm high sheet iron bottom cap . This was already available at Pottet / Schneider. On top of this, Boxer put a second, 7 mm high base cap made of sheet brass. This was followed by a 1.27 mm thick base plate made of painted iron. The bottom caps and the bottom plate were held together by a hollow rivet ; this hollow rivet also served as an ignition bell. Boxer also modified the original Pottet / Schneider ignition. To do this, Boxer changed the anvil so that it could lean on the front edge of the primer . This construction became known as the boxer ignition . Production started in 1866 at the Royal Arsenal and Eley. Daw took legal action against these cartridges in December 1866. In the meantime, Eley had come to an agreement with Eugène Schneider's heirs . Since the French patent was no longer protected, neither was the English patent derived from it and Daw's suit was dismissed.
The cartridge was loaded with 4.5 g of black powder and fitted with a 31 g mini-bullet . The bullet had a hollow point , a conical expansion space and four fat grooves . The purpose of the hollow point was to give the bullet a more elongated shape without adding weight. The conical expansion chamber was closed with a plug made of clay . Due to the large caliber, the bullet received a relatively low twist and was thus the weak point of the construction. To alleviate this problem, the bullet shape and weight were changed several times; lighter bullets achieved higher muzzle velocities. The cartridge case was also subject to changes; it was later rolled from sheet brass and later deep-drawn like modern sleeves .
The .577 / 450 Martini-Henry cartridge for the Martini-Henry rifle was developed from the .577 Snider . In addition, the case was given a shoulder to accommodate a smaller projectile; the sleeve then corresponded to a bottle neck sleeve .
use
In addition to the main use of the cartridge in British military rifles, it was also used in hunting rifles and Howdah pistols for hunting big game .
