Lee–Metford
The Lee–Metford rifle (a.k.a. ''Magazine Lee–Metford'', abbreviated ''MLM'') was a bolt-action British army service rifle, combining James Paris Lee's rear-locking bolt system and detachable magazine with an innovative seven groove rifled barrel designed by William Ellis Metford. It replaced the Martini–Henry rifle in 1888, following nine years of development and trials, but remained in service for only a short time until replaced by the similar Lee–Enfield. Design Lee's bolt action mechanism was a great improvement over other designs of the day: - The rear-mounted lugs placed the operating handle much closer to the rifleman, over the trigger. This made it much quicker to operate than other, forward-mounted lug designs which forced the rifleman to move his hand forward to operate the bolt. It also enabled the rifleman to operate the trigger with his middle finger while still holding the bolt between thumb and index finger. - The bolt's distance of travel was identic ...

Lee–Enfield
The Lee–Enfield or Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the British Army's standard rifle from its official adoption in 1895 until 1957. The WWI versions are often referred to as the "SMLE", which is short for the common "Short, Magazine, Lee–Enfield" variant. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded the earlier Martini–Henry, Martini–Enfield, and Lee-Metford rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard issue weapon to rifle companies of the British Army, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars (such ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

James Paris Lee
James Paris Lee (9 August 1831 – 24 February 1904) was a British Canadian and later American inventor and arms designer. He is best known for having invented the action and magazine that are used in the Lee–Metford and Lee–Enfield series of rifles. Early life and career Born in Hawick, Scotland, Lee emigrated with his family to Galt, Ontario, in Canada in 1836 at age 5. He built his first gun at the age of 12, using an old horse-pistol barrel, a newly carved walnut stock, and a priming pan made from a halfpenny. The gun failed to function effectively when first fired, but started Lee's interest in gunsmithing and invention. In 1858, James Lee and his wife Caroline Lee (née Chrysler, of the later automotive family) moved to Wisconsin in the US, where they had two sons: William (born in 1859) and George (1860). In 1861, Lee developed a breech loading cartridge conversion for the Springfield Model 1861 rifle musket, managing to acquire a contract for 1,000 rifles from ...

Polygonal Rifling
Polygonal rifling ( ) is a type of gun barrel rifling where the traditional sharp-edged "lands and grooves" are replaced by less pronounced "hills and valleys", so the barrel bore has a polygonal (usually hexagonal or octagonal) cross-sectional profile. Polygonal riflings with a larger number of edges have shallower corners, which provide a better gas seal in relatively large diameter bores. For instance, in the pre-Gen 5 Glock pistols, octagonal rifling is used in the large diameter .45 ACP bore, which has an 11.23 mm (0.442 in) diameter, since it resembles a circle more closely than the hexagonal rifling used in smaller diameter bores.Barrel History History [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martini–Henry
The Martini–Henry is a breech-loading single-shot rifle with a lever action that was used by the British Army. It first entered service in 1871, eventually replacing the Snider–Enfield, a muzzle-loader converted to the cartridge system. Martini–Henry variants were used throughout the British Empire for 47 years. It combined the dropping-block action first developed by Henry O. Peabody (in his Peabody rifle) and improved by the Swiss designer Friedrich von Martini, combined with the polygonal rifling designed by Scotsman Alexander Henry. Though the Snider was the first breechloader firing a metallic cartridge in regular British service, the Martini was designed from the outset as a breechloader and was both faster firing and had a longer range. There were four main marks of the Martini–Henry rifle produced: Mark I (released in June 1871), Mark II, Mark III, and Mark IV. There was also an 1877 carbine version with variations that included a Garrison Artillery Carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Ellis Metford
William Ellis Metford (4 October 1824 – 14 October 1899) was a British engineer best known for designing the Metford rifling used in the .303 calibre Lee–Metford and Martini–Metford service rifles in the late 19th century. Life He was born on 4 October 1824, the elder son of William Metford, a physician, of Flook House, Taunton, by his wife, Mary Eliza Anderdon. He was educated at Sherborne School between 1838 and 1841, and was apprenticed to W. M. Peniston, resident engineer under Isambard Kingdom Brunel, on the Bristol and Exeter Railway. From 1846 to 1850, he was employed on the Wilts, Somerset and Weymouth Railway. After 1850, he worked for Thomas Evans Blackwell, in connection with schemes for developing the traffic of Bristol, and subsequently acted for a short time under Peniston as engineer on the Wycombe railway, residing at Bourne End. During this period, he designed an improved theodolite with a travelling stage and a curved arm upholding the transit axis, a ...

Bolt-action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves ( rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile ( bullet) is propelled by the contained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smokeless Powder
Finnish smokeless powderSmokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to gunpowder ("black powder"). The combustion products are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel. Despite its name, smokeless powder is not completely free of smoke; while there may be little noticeable smoke from small-arms ammunition, smoke from artillery fire can be substantial. Originally invented in 1884 by Paul Vieille, the most common formulations are based on nitrocellulose, but the term was also used to describe various picrate mixtures with nitrate, chlorate, or dichromate oxidizers during the late 19th century, before the advantages of nitrocell ...
