.577 Snider
The .577 Snider cartridge was a British black powder metallic rimfire cartridge, which fired a , lead projectile, primarily used in the Snider–Enfield rifle. Early .577 Snider cartridges were made from a composite design using paper and brass foil with a stamped metallic base and primer, much like the first generation of Martini-Henry cartridges. Later cartridges (after the design had been proved with the Martini-Henry cartridges) were made from drawn brass, much like modern small arms ammunition. The .577 Snider cartridge was eventually replaced in service by the .577/450 Martini–Henry cartridge in the 1870s. The .577 Snider cartridge is considered by most commentators to be obsolete, with large scale commercial production having ceased in the 1930s. However, as of 2012, cases, bullets and cartridges as well as others of the .577 family are available from Tenbury Guns Limited (company dissolved 31 May 2016) in the United Kingdom. New brass can be formed from a 24 gauge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zulu War
The Anglo-Zulu War was fought in 1879 between the British Empire and the Zulu Kingdom. Following the passing of the British North America Act of 1867 forming a federation in Canada, Lord Carnarvon thought that a similar political effort, coupled with military campaigns, might succeed with the African Kingdoms, tribal areas and Boer republics in South Africa. In 1874, Sir Bartle Frere was sent to South Africa as High Commissioner for the British Empire to effect such plans. Among the obstacles were the armed independent states of the South African Republic and the Kingdom of Zululand.Knight (1992, 2002), p. 8. Frere, on his own initiative, sent a provocative ultimatum on 11 December 1878 to the Zulu king Cetshwayo and upon its rejection sent Lord Chelmsford to invade Zululand. The war is notable for several particularly bloody battles, including an opening victory of the Zulu at the Battle of Isandlwana, followed by the defence of Rorke's Drift by a small British force ...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin ( pinfire, now obsolete); or ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate ( saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snider–Enfield
The British .577 Snider–Enfield was a breech-loading rifle. The American Jacob Snider invented this firearm action, and the Snider–Enfield was one of the most widely used of the Snider varieties. The British Army adopted it in 1866 as a conversion system for its ubiquitous Pattern 1853 Enfield muzzle-loading rifles, and used it until 1874 when the Martini–Henry rifle began to supersede it. The British Indian Army used the Snider–Enfield until the end of the nineteenth century. Design and manufacture In trials, the Snider Pattern 1853 conversions proved both more accurate than the original Pattern 1853s and much faster firing; a trained soldier could fire ten aimed rounds per minute with the breech-loader, compared with only three rounds per minute with the muzzle-loading weapon. From 1866 onwards, the Enfield rifles were converted in large numbers at the Royal Small Arms Factory (RSAF) Enfield beginning with the initial pattern, the Mark I. The converted rifles receiv ...

Small Arms
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obsolete
Obsolescence is the state of being which occurs when an object, service, or practice is no longer maintained or required even though it may still be in good working order. It usually happens when something that is more efficient or less risky replaces it. The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification". Obsolete also refers to something that is already disused or discarded, or antiquated. Typically, obsolescence is preceded by a gradual decline in popularity. Consequences Driven by rapid technological changes, new components are developed and launched on the market with increasing speed. The result is a dramatic change in production methods of all components and their market availability. A growing industry sector is facing issues where life cycles of products no longer fit together with life cycles of required components ...

Kynoch
Kynoch was a manufacturer of ammunition, later incorporated into ICI but remaining as a brand name for sporting cartridges. History The firm of Pursall and Phillips operated a 'percussion cap manufactory' at Whittall Street, in Birmingham, in the mid 19th century. In 1856, Scottish entrepreneur George Kynoch joined the company. An explosion in 1859 destroyed the works, killing 19 of the 70 employees. As a result, the firm moved to Witton in 1862, on a site adjacent to the London and North Western Railway's Grand Junction line. In 1863, Kynoch took over the business, which was subsequently renamed G. Kynoch and Co. A further series of explosions in the 1860s and in 1870 led to dozens of deaths and hundreds of injuries. In 1895 Kynoch built an explosives factory east of Shell Haven Creek, Essex (now known as Coryton). This opened in 1897, with an estate for employees called Kynochtown. Products included cordite, guncotton, gunpowder, and cartridges. After World War I many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
