.458 SOCOM
The .458 SOCOM (11.63×40mmRB) is a moderately large round designed to work in an AR-15 platform. This is achieved by installing a 458 bolt and barrel. The round offers a muzzle velocity of and , similar to a light .45-70 but with a much smaller case. History Prompted by the lack of power offered by the 5.56 NATO cartridge used in the M4 carbine and the M16 rifle, the .458 SOCOM came about from informal discussion of members of the special operations command, specifically Task Force Ranger's experience that multiple shots were required to incapacitate members of the opposing force in Mogadishu during Operation Gothic Serpent. Marty ter Weeme of Teppo Jutsu and Tony Rumore of Tromix designed the cartridge in 2000 and Tromix was contracted to build the first .458 SOCOM rifle in February 2001. The project sponsor set forth a number of requirements including that the cartridge fit in the M4 carbine and be capable of firing heavy-for-caliber projectiles at subsonic velocity using ...

308 Winchester
The .308 Winchester is a smokeless powder Rim (firearms), rimless bottlenecked rifle Cartridge (firearms), 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 7.62×51mm NATO#Development, 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. mi ...

50 Beowulf
The .50 Beowulf (12.7x42mmRB) is a 12mm caliber rifle cartridge developed by Bill Alexander of Alexander Arms for use in an AR-15 rifle. Design and specifications The cartridge utilizes a rebated rim, sized to match the rim of the 6.5mm Grendel round. The case body is very similar in dimensions to the .500 S&W Magnum revolver cartridge, being slightly longer and fully tapered for automatic feeding in the weapon. The round is intended to improve stopping power greatly at short- to medium-range as compared to the standard 5.56×45mm NATO round. One of its advertised uses is at vehicle checkpoints, since the heavy bullet's flight path is not easily deflected by auto glass or standard vehicle body panels. Design limitations With normal bullet weights between , overall cartridge length shorter than that of an AR-15 magazine well, and holding to pressures of 33,000 psi limited by the AR bolt strength system, the .50 Beowulf is best described as a low-velocity, heavy caliber, ...

45 Raptor
The 45 Raptor (11.5x46mm) is a rimless centerfire cartridge developed for the AR-10 semi-automatic rifle for medium and large game hunting. Compared to similar big bore cartridges designed for the AR-15such as the .450 Bushmaster, .458 SOCOM, and .50 Beowulf the 45 Raptor offers higher velocity bullets, a flatter shooting trajectory and the ability to reliably feed hollow point ammunition.45 Raptor Ballistic Chart " History Introduced in April 2014, the 45 Raptor was created by Arne Brennan.New Cartridge: 45 RaptorBrennan is also known for his prior work with the 6.5 ...

375 SOCOM
The .375 SOCOM (9.5x40mmRB) round is a custom developed round created by Tony Rumore of Tromix Lead Delivery Systems. Cases are formed from .458 SOCOM run through a custom .375 SOCOM sizing die. History The .375 SOCOM is a fairly new cartridge, designed by Tromix in 2015. Taking a .458 SOCOM cartridge case and sizing the neck down to .375 caliber, resulted in a hard hitting AR-15 compatible cartridge, that has a considerable velocity and range advantage over the .458 SOCOM as well as other big bore AR-15 cartridges. Unknown to most, the .375 SOCOM has a sizeable case capacity, nearly 60 grains, but safe handloading should start near 40 grains. Typical .375 SOCOM loads will launch a 200 grain bullet 2400 feet per second from a 20" barrel. In a short barrel suppressed subsonic application, the .375 SOCOM can be made to easily cycle the AR-15 action, using fairly fast burning propellants such as IMR 700X, Trail Boss and VV N32C (Tin Star). This can be problematic with the . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
458 Winchester Magnum
The .458 Winchester Magnum is a belted, straight-taper cased, Big Five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle. It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition. History The .458 Winchester Magnum was designed for hunting dangerous game animals by emulating the performance of powerful English double rifle cartridges in a bolt-action rifle. The use of a bolt-action rifle offered hunters a cheaper alternative to the big-bore double rifle, and ammunition could be manufactured using available tooling. The .458 Winchester Magnum soon became a success as dangerous game hunters adopted the cartridge. Soon, game wardens, wildlife managers, and ...
