Fully Powered Cartridge
A fully powered cartridge, also called full-power cartridge or full-size cartridge, is an umbrella term describing any rifle cartridge with a caliber greater than , a maximum effective range of at least , and intended for engaging targets (large game animals) beyond . The term generally refers to traditional cartridges used in machine guns and bolt action and semi-automatic service rifles and select fire battle rifles prior to, during, and immediately after the World Wars and the early Cold War era, and was a retronym originally made to differentiate from intermediate cartridges that gained widespread adoption into military service after World War II. Most modern fully powered cartridges have their origin in the late 19th century and early 20th century with the advent of smokeless powder. Examples include the 6.5×55mm Swedish, 7×57mm Mauser, 7.5×55mm Swiss, 7.5×54mm French, 7.62×51mm NATO, 7.62×54mmR, .30-06 Springfield, .303 British, 7.65×53mm Mauser, 7.7×58mm Arisa ...

7×57mm Mauser
The 7×57mm Mauser (designated as the 7 mm Mauser or 7×57mm by the SAAMI and 7 × 57 by the C.I.P.) is a first-generation smokeless powder rimless bottlenecked rifle cartridge. It was developed by Paul Mauser of the Mauser company in 1892 and adopted as a military cartridge by Spain in 1893.Jim Wilson "A Perfectly Delightful Cartridge: 7×57 mm Mauser" ''American Rifleman'' November 2009 pp.53–55 It was subsequently adopted by several other countries as the standard military cartridge, and although now obsolete as a military cartridge, it remains in widespread international use as a sporting round. The 7×57 Mauser (originally known in Britain as the .275) was a popular stalking cartridge and sporting rifles in this chambering were made by the famous British riflemakers, such as John Rigby, Holland and Holland, Westley Richards and others. British cartridge nomenclature designated caliber in inches, and the cartridge was known as the .275 bore after the measurement of a ...

20th Century
The 20th (twentieth) century began on January 1, 1901 ( MCMI), and ended on December 31, 2000 ( MM). The 20th century was dominated by significant events that defined the modern era: Spanish flu pandemic, World War I and World War II, nuclear weapons, nuclear power and space exploration, nationalism and decolonization, technological advances, and the Cold War and post-Cold War conflicts. These reshaped the political and social structure of the globe. The 20th century saw a massive transformation of humanity's relationship with the natural world. Global population, sea level rise, and ecological collapses increased while competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others. Global heating increased the risk of extreme weather conditions. Additional themes include intergovernmental organizations and cultural homogenization through developments in em ...

Hunting 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 deflagrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Purpose Machine Gun
A general-purpose machine gun (GPMG) is an air-cooled, usually belt-fed machine gun that can be adapted flexibly to various tactical roles for light and medium machine guns. A GPMG typically features a quick-change barrel design calibered for various fully powered cartridges such as the 7.62×51mm NATO, 7.62×54mmR, 7.5×54mm French, 7.5×55mm Swiss and 7.92×57mm Mauser, and be configured for mounting to different stabilizing platforms from bipods and tripods to vehicles, aircraft, boats and fortifications, usually as an infantry support weapon or squad automatic weapon. History The general-purpose machine gun (GPMG) originated with the MG 34, designed in 1934 by Heinrich Vollmer of Mauser on the commission of Nazi Germany to circumvent the restrictions on machine guns imposed by the Treaty of Versailles. It was introduced into the Wehrmacht as an entirely new concept in automatic firepower, dubbed the ''Einheitsmaschinengewehr'', meaning "universal machine gun" in Germ ...

Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to bite into the rifling grooves as was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Designated Marksman Rifle
A designated marksman rifle (DMR) is a modern telescopic sight, scoped high-Accuracy and precision, precision rifle used by infantrymen in the designated marksman (DM) role. It generally fills the engagement effective range, range gap between a service rifle and a dedicated sniper rifle, at around . DMRs, unlike the often bolt-action sniper rifles, are semi-automatic rifle, semi-automatic as these have higher rate of fire, rates of fire and typically larger magazine (firearms), magazine capacities (10, 20, or 30 rounds depending on the firearm and operational requirements) to allow rapid engagement of multiple targets. These rifles have to be effective, in terms of probability of kill, hit rates and terminal ballistics, at application ranges exceeding those of ordinary assault rifles and battle rifles, but do not require the extended-range performance of a dedicated sniper rifle. DMRs need to function as part of squad (and possibly at close quarters) and often share some basic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Next Generation Squad Weapon Program
The Next Generation Squad Weapon (NGSW) program is a United States military program created in 2017 to replace the 5.56mm M4 carbine and M249 SAW light machine gun and the 7.62mm M240 machine gun, with a common system of 6.8mm cartridges; and to develop small arms fire control systems for the new weapons. Seven defense manufacturers competed in the program, with five attempting to design and produce the weapons; two attempting to create and supply fire control optics. The U.S. Army officially announced the winners in early 2022; SIG Sauer to produce the XM5 rifle and XM250 automatic rifle, Vortex Optics to produce the XM157 fire control system, and Winchester produce the custom 6.8mm ammunition cartridges designed by SIG Sauer. The program was expected to cost $10 million in the first year of production, and $150 million the next. History The NGSW program began in 2017, after the U.S. Congress issued an order for the U.S. Army to conduct an assessment regarding the need to u ...
