8.6×70mm
The .338 Lapua Magnum (8.6×70 mm or 8.58×70 mm) is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. It was used in the War in Afghanistan and the Iraq War. As a result of this, it has become widely available. The loaded .338 cartridge is in diameter (rim) and long. It can penetrate better-than-standard military body armor at ranges of up to , and has a maximum effective range of about with C.I.P. conforming ammunition at sea level conditions. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from for commercial loads with bullets, which corresponds to about of muzzle energy. British military issue overpressure .338 Lapua Magnum cartridges with overall length, loaded with LockBase B408 very-low-drag bullets fired at 936 m/s (3,071 ft/s) muzzle velocity fired from a L115A3 Long Range Rifle were used in November 2009 ...

Accuracy International AWM
The Accuracy International AWM (Arctic Warfare Magnum or AI-Arctic Warfare Magnum) is a bolt-action sniper rifle manufactured by Accuracy International designed for magnum rifle cartridges. The Accuracy International AWM is also unofficially known as the AWSM (Arctic Warfare Super Magnum), which typically denotes AWM rifles chambered in .338 Lapua Magnum. On 9 September 2012, Accuracy International announced that the .338 Lapua Magnum AWM rifle was phased out and replaced by the Accuracy International AXMC sniper rifle. The bolt action of the AXMC was designed to be significantly stronger and more capable of handling higher chamber pressures and temperatures and thus higher bolt thrust safely compared to the AWM and hence is longer and wider. The AXMC magazine was also appropriately enlarged to function with .338 Lapua Magnum cartridges loaded to the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives (C.I.P.) maximum allowed overall length of .

338 Norma Magnum
__NOTOC__ Year 338 ( CCCXXXVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Ursus and Polemius (or, less frequently, year 1091 ''Ab urbe condita''). The denomination 338 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Big-game Hunter
Big-game hunting is the hunting of large game animals for meat, commercially valuable by-products (such as horns/antlers, furs, tusks, bones, body fat/oil, or special organs and contents), trophy/taxidermy, or simply just for recreation ("sporting"). The term is often associated with the hunting of Africa's "Big Five" games (lion, African elephant, Cape buffalo, African leopard, and rhinoceros), and with tigers and rhinoceroses on the Indian subcontinent. History Hunting of big game for food is an ancient practice, possibly arising with the emergence of ''Homo sapiens'' (anatomically modern humans), and possibly pre-dating it, given the known propensity of other great apes to hunt, and even eat their own species. The Schöningen spears and their correlation of finds are evidence that complex technological skills already existed 300,000 years ago, and are the first obvious proof of an active (big game) hunt. ''H. heidelbergensis'' already had intellectual and cognitiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Deformation
In engineering, deformation refers to the change in size or shape of an object. ''Displacements'' are the ''absolute'' change in position of a point on the object. Deflection is the relative change in external displacements on an object. Strain is the ''relative'' internal change in shape of an infinitesimally small cube of material and can be expressed as a non-dimensional change in length or angle of distortion of the cube. Strains are related to the forces acting on the cube, which are known as stress, by a stress-strain curve. The relationship between stress and strain is generally linear and reversible up until the yield point and the deformation is elastic. The linear relationship for a material is known as Young's modulus. Above the yield point, some degree of permanent distortion remains after unloading and is termed plastic deformation. The determination of the stress and strain throughout a solid object is given by the field of strength of materials and for a st ...

Hornady
Hornady Manufacturing Company is an American manufacturer of ammunition cartridges, components and handloading equipments, based in Grand Island, Nebraska. History The company is currently run by Joyce Hornady's son, Steve Hornady, who took over after his father's death in a plane crash on January 15, 1981. The Piper Aztec, with Hornady at the controls flying in heavy fog, crashed into Lake Pontchartrain while on final approach to New Orleans Lakefront Airport. Pacific Tool Company Steve Hornady worked for Pacific Tool Company from 1960 to 1971, from the time the company moved from California to Nebraska until Pacific Tool was bought by Hornady.

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 nitrocellu ...

Cordite
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace black powder as a military propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun. Cordite was used initially in the .303 British, Mark I and II, standard rifle cartridge between 1891 and 1915; shortages of cordite in World War I led to the creation of the "Devil's Porridge" munitions factory ( HM Factory, Gretna) on the English-Scottish border, which produced 800 tonnes of cordite per annum. The UK also imported some United States–developed smokeless powder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penetration (weapons)
Strictly speaking, penetration occurs when a projectile enters a target without passing through it and perforation occurs when the projectile completely passes through the target, but the word ''penetration'' is commonly used to refer to either. Penetration into a ''semi-infinite'' or ''massive'' target is penetration (in the strict sense of the word) of targets so thick that the level of penetration is not affected by the target's thickness. There is a ''transition region'' between semi-infinite penetration and perforation, in which the target is not perforated but the projectile, as it nears the back face of the target, meets reduced resistance and is capable of penetrating a greater distance than it would in a semi-infinite target. This effect is variously named the back or rear surface, plate, or face effect and is also present when perforation occurs. A penetrating projectile may cause the target to break into multiple pieces, spewing from both the front and back of the targ ...
