디자인 및 사양

The cartridge utilizes a rebated rim, sized to match the rim of the 7.62×39mm and 6.5mm Grendel rounds. 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 300 and 400 grains (19 and 26 g), 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,[2] the .50 Beowulf is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of early .45-70 Government rounds rather than the higher pressure rounds tolerated by lever-action rifles such as the Marlin Model 1895.[3] Adaptability is limited due to its use of the 7.62×39mm bolt face.[4]

Proprietary status

The .50 Beowulf is a proprietary caliber developed as a specialized cartridge. Alexander Arms and Delta Firearms oversees all aspects of the production of the system and related accessories. Their reluctance to divulge information has been a source of irritation to some writers.[3] Because Alexander Arms holds a trademark on the name .50 Beowulf, a number of other companies produce weapons and ammunition reverse engineered to the same dimensions under the name 12.7x42mm.

Sporting uses

Although much has been written about its tactical uses, the .50 Beowulf is gaining recognition as a sporting cartridge. It is becoming more widely recognized as being usable for a wide variety of North American game,[5] including deer, moose, and black bear.[3]

Similar cartridges

The cartridge has its lineage in the .50 Action Express, starting with the L.A.R. Grizzly and in modern times, the Magnum Research Desert Eagle pistol, with significant modification to improve functionality and safety in the AR-15 rifle.[6]
