.308
The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar, but not identical, to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated "T65" and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. military .30-06 Springfield service cartridge.

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, 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 convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

30-06
The .30-06 Springfield cartridge (pronounced "thirty- aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1 ...

300 Savage
The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by Savage Arms in 1920. It was designed to replace the less powerful .303 Savage in their popular Savage Model 1899 hammerless lever-action rifle, which they started to produce again as Model 99, as well as the new Savage Model 1920 bolt-action rifle. Despite having a short case in order to fit the original Model 99 magazine and a rather stumpy neck, the cartridge is capable of propelling a bullet at over with an effective range of over .

Colt Canada C19
The Colt Canada C19 is a licence-built, Finnish-designed Tikka T3 CTR bolt-action rifle modified for the Canadian Rangers. The C19 replaced the longer and heavier Lee-Enfield No. 4 Mk.1 .303" rifles which entered service with the Canadian Army in WWII and later, with the Canadian Rangers, when they were formed in 1947. After testing different submissions from rifle manufacturers, the C19 was selected as the winner of a Canadian military procurement program requesting a new bolt-action rifle with iron sights and a detachable 10-round box magazine and other requirements. The procurement program stipulated the rifles had to be produced by a Canadian manufacturer and could not be totally identical to commercial rifles. According to SAKO, production commenced in mid-2016, with rifle trials into 2017 and the full complement were expected to be delivered by the end of 2019. The rifles are mainly used for self-defence against large North American carnivores, including polar bears, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winchester Rifle
Winchester rifle is a comprehensive term describing a series of lever action repeating rifles manufactured by the Winchester Repeating Arms Company. Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters. The Model 1873 was particularly successful, being marketed by the manufacturer as "The Gun That Won the West". Predecessors In 1848, Walter Hunt of New York patented his "Volition Repeating Rifle" incorporating a tubular magazine, which was operated by two levers and complex linkages. The Hunt rifle fired what he called the " Rocket Ball", an early form of caseless ammunition in which the powder charge was contained in the bullet's hollow base. Hunt's design was fragile and unworkable, but in 1849, Lewis Jennings purchased the Hunt patents and developed a functioning, if still complex rifle. This version was produced in small numbers by Robbins & Lawrence of Windsor, Vermont until 1852. Horace Smith and Daniel Wesson of Norwich, Conn ...

Rim (firearms)
A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge. Types There are various types of firearms rims in use in modern ammunition. The main types are categorized as rimmed, rimless, semi-rimmed, rebated, and belted. These describe the size of the rim in relation to the base of the case. Rimmed The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is significantly larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the (usually straight sided) cartridge in the chamber of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Rangers
The Canadian Rangers () are a sub-component of the Canadian Army Reserve under Canadian Armed Forces reserves that provides a limited military presence in regions of Canada where stationing conventional Army units would not be practical or economically viable. Formally established on May 23, 1947, the Canadian Rangers employs around 5,000 Rangers. The Canadian Rangers are responsible for remote, isolated, and sparsely populated regions of Canada, such as Northern Canada and the coastlines. They regularly conduct surveillance, sovereignty patrols (SOVPATS), and inspections of the North Warning System. They also act as guides, scouts, and subject-matter experts in such disciplines as wilderness survival when other forces and Army components are in their area of operations. Organization The Canadian Rangers are a unit of the Canadian Armed Forces Army Reserve made up of a diverse group of Canadians. Though there is a misconception that the Canadian Rangers is a First Nations u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifling
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nb ...

Winchester Repeating Arms Company
The Winchester Repeating Arms Company was a prominent American manufacturer of repeating firearms and ammunition. The firm was established in 1866 by Oliver Winchester and was located in New Haven, Connecticut. The firm went into receivership in 1931 and was bought by the Western Cartridge Company, a forerunner of the Olin Corporation. The Winchester brand name is still owned by the Olin Corporation, which makes ammunition under that name. The Winchester name is also used under license for firearms produced by two subsidiaries of the Herstal Group – FN Herstal of Belgium and the Browning Arms Company of Ogden, Utah. History Early history Predecessors The ancestor of the Winchester Repeating Arms Company was the Horace Smith and Daniel Wesson partnership of Norwich, Connecticut (not to be confused with the famous Smith & Wesson Revolver Company founded later by the same men). Smith and Wesson acquired Lewis Jennings' improved version of inventor Walter Hunt's 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action (firearms)
In firearms terminology, an action is the functional mechanism of a breechloading firearm that handles (loads, locks, fires, extracts, and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, wheellock, flintlock, and caplock). Actions can be categorized in several ways, including single action versus double action, break action versus lever-action, pump-action, bolt-action, among many other types. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , ...

Sniper Rifle
A sniper rifle is a high-precision, long range shooting, long-range rifle. Requirements include high accuracy, reliability, mobility, concealment, and optics, for anti-personnel weapon, anti-personnel, anti-materiel rifle, anti-materiel and surveillance uses by military snipers. The modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic firearm, semi-automatic action (firearms), action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance Centerfire ammunition, centerfire cartridge (firearms), cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed in 1854 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 with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
