Rifle Cartridge
A rifle cartridge is a firearm cartridge (firearms), cartridge primarily designed and intended for use in a rifle/carbine, or machine gun. Types Full-powered A full-powered cartridge is a rifle cartridge used interchangeably between service rifles, sniper rifles, and general purpose machine guns. It is a retronym for rifle cartridges used prior to and during World War II. They are primarily used today in general purpose machine guns, designated marksman rifles, and sniper rifles. Magnum A magnum cartridge is a cartridge with a larger case size than, or derived from, a similar cartridge of the same bullet caliber and case shoulder shape. Magnum cartridges allow for more propellant to be loaded within the casing, and thus have a higher muzzle energy. Modern magnum rifle cartridges include .300 RUM, 7mm Remington Magnum, .300 Weatherby Magnum, .460 Weatherby Magnum, .300 Winchester Magnum, .338 Lapua Magnum or .338 Norma Magnum. Today they are primarily used in civilian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle Cartridge Comparison
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling 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 in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

7mm Remington Magnum
The 7mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, along with the new Remington Model 700 bolt-action rifle. It is a member of the belted magnum family that is directly derived from the venerable .375 H&H Magnum.Speer Reloading Manual The original purpose of the belted magnum concept taken from the .300 H&H Magnum and .375 H&H Magnum, was to provide precise headspace control, since the sloping shoulders, while easing cartridge extraction, were unsuitable for this purpose. Improved cartridge extraction reliability is desirable while hunting dangerous game, in particular when a fast follow-up shot is required. The 7mm Remington Magnum is based on the commercial .264 Winchester Magnum, .338 Winchester Magnum, and .458 Winchester Magnum, which were based on the same belted .300 H&H Magnum and .375 H&H Magnum cases, trimmed to nearly the same length as the .270 Weatherby Magnum.

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, for according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. Basics Any launching system (weapon or not) generates recoil. However recoil only constitutes a problem in the field of artillery and firearms due to the magnitude of the forces at play. Gun chamber pressures and projectile acceleration forces are tremendous, on the order of tens to hundreds mega pascalAs a perspective, the atmospheric pressure is roughly 0.1 megapascal. and tens of thousands of times the acceleration of gravity ( g's), both necessary to launch the projectile a ...

Submachine Gun
A submachine gun (SMG) is a magazine (firearms), magazine-fed automatic firearm, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix "wikt:sub-, sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a Close-quarters battle, close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of submachine guns were made for shock troops, assault troops and auxiliaries whose military doctrine, doctrines emphasized close-quarters combat, close-quarter suppressive fire. New submachine gun designs appeared frequently during the Cold War,Military Small Arms Of The 20th Century. Ian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Pistol
A service pistol (also known as a standard-issue pistol or a personal ordnance weapon) is any handgun issued to regular military personnel or law enforcement officers. Typically, service pistols are semi-automatic pistols (previously revolvers) issued to Officer (armed forces), officers, non-commissioned officers, and rear-echelon support personnel for self-defence, though service pistols may also be issued to special forces as a backup for their primary weapons. Pistols are not typically issued to front-line infantry. Before firearms were commonplace, officers and non-commissioned officers typically carried swords. History Prior to the introduction of cartridge-loading firearms, there was little standardization with regard to the handguns carried by military personnel, although it had been important for Officer (armed forces), officers, artillerymen, and other auxiliary troops to have a means of defending themselves, especially as it was not always practical for them to have a f ...

30-06 Springfield
The .30-06 Springfield cartridge (weaponry), cartridge (pronounced "thirty-Names for the number 0 in English, 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 standardization, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Range Shooting
Long range shooting is a collective term for shooting sport, shooting disciplines where the distance to the target is significant enough that the shooter has to put effort into calculating external ballistics, various ballistic factors, especially in regards to the deviating effects of gravity and wind. While shooting at shorter ranges, a shooter only has to slightly adjust the sight (device), sights to compensate for limited bullet drop at most, but when the range is extended, wind drift will be the first factor affecting precision to the extent that it must be taken into serious account. Some would argue that long range shooting starts where assessment of wind, distance and various atmospheric conditions are equally important for the results as pure shooting skills - meaning that even if one conducts a technically perfect shot, the shooter will miss the target because of incorrect calculations, neglecting to take some elements into consideration, or merely due to unpredic ...

Ammunition
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected Targeting (warfare), target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm Cartridge (firearms), cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big-game Hunting
Big-game hunting is the hunting of large game animals for trophies, taxidermy, meat, and commercially valuable animal by-products (such as horns, antlers, tusks, bones, fur, body fat, or special organs). The term is often associated with the hunting of Africa's "Big Five" game (lion, African elephant, Cape buffalo, African leopard, and African rhinoceros), and Indian rhinoceros and Bengal tigers 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 cognitive skills like anticipatory plannin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
338 Norma Magnum
The .338 Norma Magnum is a cartridge first introduced in 2008 and came into production in 2009, designed by Norma of Sweden. Design history The .338 Norma Magnum was originally developed as a long-range sport shooting wildcat cartridge by the American sport shooter Jimmie Sloan with the help of Dave Kiff, owner of Pacific Tool and Gauge, who made the reamers and headspace gauges. Barrels were supplied by Rock Creek Barrel Inc. Various twist rates were tried with 5R rifling. It was designed as a way to optimize shooting the caliber Sierra HPBT MatchKing projectile from actions and magazines that lack the length to handle cartridges exceeding in overall length. The caliber Sierra HPBT MatchKing projectile was not available when the .338 Lapua Magnum was originally designed (it was optimized for shooting 16.2 g (250 gr) projectiles) and .338 Lapua Magnum cartridges intended for military use are generally loaded with shorter 16.2 g (250 gr) to 18.47 g (285 gr) projectiles.

338 Lapua Magnum
The .338 Lapua Magnum (8.6×70mm or 8.58×70mm) is a Finland, Finnish rimless, bottlenecked, centerfire rifle cartridge (firearms), cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. Due to its use in the War in Afghanistan (2001–2021), War in Afghanistan and the Iraq War, the cartridge has become widely available. The cartridge is named after Finnish town Lapua. 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 Commission internationale permanente pour l'épreuve des armes à feu portatives, 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.
