.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, ...

50 Action Express
The .50 Action Express (AE) (12.7×33mmRB) is a large-caliber handgun cartridge, best known for its usage in the Desert Eagle. Developed in 1988 by American Evan Whildin of Action Arms, the .50 AE is one of the most powerful pistol cartridges in production. Overview The actual cartridge has a base, with a rebated rim. The rim diameter of the .50 AE is the same as the .44 Remington Magnum cartridge. A Mark XIX Desert Eagle in .50 AE can be converted to .44 with nothing more than a barrel and magazine change. The introduction of the .50 AE in the United States was met with a rocky start. Federal firearms statutes state that non-sporting firearms may not be over 0.500 inches in bore diameter (measured land to land) to meet Title I regulations. The original .50 AE bore diameter was .500 in, with conventional rifling, but the switch to polygonal rifling on production Desert Eagles allowed the gauge plug to drop through, rendering the gun a destructive device under Bureau of Alco ...

LAR Grizzly Win Mag
The Grizzly Win Mag pistols were conceived, invented, designed, engineered and developed in the 1980s by the sole inventor, Perry Arnett, who licensed his patent for an interchangeable caliber semi-automatic pistol to L.A.R. Manufacturing Inc. Perry Arnett's designs were initially flawed and were improved upon by Heinz Augat (former owner and founder of L.A.R. Manufacturing Inc.). Background The LAR Grizzly pistol was a modified Colt M1911 style pistol with oversized components designed to handle larger, more powerful cartridges than could be used in the standard-size 1911 pistol. The original prototype built by Perry Arnett was made from two Colt 1911 frames and slides cut and welded to accommodate the .45 Winchester Magnum round, with two steel doubler plates welded to the slide flats to retard the action and increase strength. Between 1983 and 1999, approximately 15,000 guns were produced in four versions capable of firing six different cartridges. All guns were hand-fitted and ...

List Of Rebated Rim Cartridges
Below is a list of rebated rim cartridges. Rebated-rim cartridges have a rim that is significantly smaller in diameter than the base of the case, serving only for extraction. Functionally the same as a rimless case, the rebated rim allows a gun to be easily converted to fire a larger-than-normal cartridge, as most of a firearm's loading and extraction mechanism does not need to be altered as long as the rim size is preserved. Rebated-rim cartridges are known to be used on firearms using advanced primer ignition (API blowback) for its operation, notably autocannons such as the 20mm Becker/Oerlikon series. www.quarry.nildram.co.uk article The bolt face has the same diameter as the rebated-rim cartridge as it follows along with the extraction claw into ...

List Of AR Platform Cartridges
The AR platform has become widely popular for makers of hunting and sporting rifles. Although the designations "ArmaLite AR-10, AR-10" and "Colt AR-15, AR-15" are respectively trademarks of ArmaLite and Colt's Manufacturing Company, Colt, variants of both are made by many manufacturers. The AR-15 rifle usually comes chambered for either the military cartridge 5.56×45mm NATO, 5.56×45mm or the .223 Remington. Because of the pressures associated with the 5.56×45mm, it is not advisable to fire 5.56×45mm rounds in an AR-15 marked as .223 Remington, since this can result in damage to the rifle or injury to the shooter. The AR-15 can be chambered in many other calibers; it is then often referred to as an AR-15 style rifle.

450 Bushmaster
The .450 Bushmaster (11.48x43mmRB) is a rifle cartridge developed by Tim LeGendre of LeMag Firearms, and licensed to Bushmaster Firearms International. The .450 Bushmaster is designed to be used in standard M16s and AR-15s, using modified magazines and upper receiver assemblies. History The .450 Bushmaster is descended from the Thumper concept popularized by the gun writer Jeff Cooper. Cooper was dissatisfied with the small-diameter 5.56×45mm NATO (.223 Remington) of the AR-15, and envisioned a need for a large bore (.44 cal or greater) cartridge in a semi-automatic rifle to provide one-shot kills on big-game animals at 250 yards. Inspired by this, LeGendre developed his .45 Professional cartridge, and later built and delivered an AR-15 in .45 Professional to Cooper. Bushmaster requested the ammunition manufacturer Hornady to produce the .45 Professional cartridge for this project, but Hornady wanted to shorten the cartridge case and overall length to accommodate their ...
