.308×1.5-inch Barnes
The .308×1.5" Barnes is a wildcat cartridge based on the .308 Winchester (7.62×51mm NATO). The cartridge is similar to the 7.62×39mm Russian (M43) cartridge though it outperforms the Soviet cartridge.Barnes, p.188, "7.62x39 (M43) Russian", & p.135, ".308x1.5" (.308 Short)". It was designed by Frank C. Barnes in March 1961 by shortening the .308 Winchester to and giving it a shoulder angle of 20° (α=40°) similar to the parent cartridge. History The first rifles commissioned for the developmental work by Barnes for the .308×1.5" cartridge were a Swedish Model 96 Mauser with a 1 in 12 (305 mm) twist built by Les Corbet and a Remington Rolling Block with a 1 in 10 (254 mm) twist built by P.O. Ackley. Due to the weights of the bullet and the performance of the cartridge, the 1 in 12 twist became the standard by consensus. Similar cartridges Apart from experimenting with .308×1.75", the legacy of the Barnes cartridge is found in its progeny cartridges. The .30 ...

308×1
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ce ...

Tubular Magazine
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as " high-capacity magazines". Nomenclature With the increased use of semi-au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lever-action Rifle
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Lever-action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, or automatic/ selective-fire actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry and Marlin) also produce lever-action rifles. Even Colt's Mfg. Co. produced the 6403 lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt-action Rifle
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 design as a ...

Spitzer Bullet
The spitzer bullet (or spire point) is a pointed projectile that is primarily used in small-arms. The pointed nose shape, which was developed for military purposes in the late 19th and early 20th century, was a major design improvement compared to earlier rounder or flatter-tipped bullets because pointed nose shapes were less susceptible to external ballistic factors like drag. By adding a point, projectiles made for fully-powered and intermediate rifle cartridges, obtain a lower drag coefficient which makes them decelerate less rapidly. Lowering the drag coefficient leads to improved external ballistic behaviour. The development of spitzer bullets and long-range volley sights for service rifles changed military doctrines. Area targets at ranges up to could be subject to rifle fire. With improvements in machine guns at the turn of the 20th Century, the addition of clinometers meant that fixed machine gun squads could deliver plunging fire or indirect fire at more than . ...

SAAMI
The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI, pronounced "Sammy") is an association of American manufacturers of firearms, ammunition, and components. SAAMI is an accredited standards developer that publishes several American National Standards that provide safety, reliability, and interchangeability standards for commercial manufacturers of firearms, ammunition, and components. In addition, SAAMI publishes information on the safe and responsible transportation, storage, and use of those products. History The origins of SAAMI date back to World War I and the Society of American Manufacturers of Small Arms and Ammunition (SAMSAA). In 1913, the US War Department encouraged the firearms and ammunition industry to establish an organization to share new technology and establish common standards for small arms and ammunition. SAMSAA was officially formed in 1918, however became inactive by the early 1920s. By the mid-1920s the United States was still suff ...

Benchrest Shooting
Benchrest shooting is a shooting sport discipline in which high-precision rifles are rested on a table or bench — rather than being carried in the shooter's hands — while shooting at paper or steel targets, hence the name "benchrest". Both the forearm and buttstock of such a rifle are usually fully supported by bean bags, a bipod/monopod (front/rear) combination, and/or a specially designed fixture device called shooting rest (which may be one- or two-piece depending on competition rules), so that the gun can remain stably pointing at the target without needing to be held by someone. When shooting, the shooter simply sits/stands comfortably behind the table/bench, operates the action and pulls the trigger, without needing to worry about carrying any weight of the gun. This is in contrast to other shooting disciplines, where the shooter has to bear at least part of the gun's weight while holding it steady to aim, even when using support devices such as bipods, tripods or ...

7mm BR
The 7mm BR Remington, commonly called the 7mm BR or the 7mm Benchrest Remington in long form, was a cartridge developed by Remington for the Remington XP-100 single-shot bolt-action handgun. The cartridge was developed for the Unlimited Class in the sport of Metallic silhouette shooting. Later it was introduced in the Remington Model XB-40 single-shot bolt-action rifle, which was specifically designed for the benchrest shooting community. The 7mm BR is based on previous Remington benchrest cartridges 6mm BR Remington and the .22 BR Remington cartridges. These cartridges in turn trace their origin to .308 Winchester via the .308×1.5-inch Barnes cartridge. The 7mm BR was designed by merely necking up the pre-existing 6mm BR Remington to accept a .28 caliber (7 mm) bullet. The cartridge is capable of developing with a bullet or with a bullet in a barrel. As a hunting cartridge it is adequate for smaller deer species and ranges under . With lighter bullets, this cartr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
