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 against vehicles, being able to disable the engine and maintaining its trajectory when hitting windscreens or body panels. It's also advertised as being effective against body armor..50 Beowulf http://www.alexanderarms.com/beowulf.htm https://web.archive.org/web/20051223072338/http://www.alexanderarms.com/beowulf.htm 2005-12-23 2026-09-10 Alexander Arms Design limitations With normal bullet weights between 300 and 400 gr g on, 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, Cutshaw Charlie .50 caliber Beowulf Tactical Response Jul–Aug 2006 http://www.hendonpub.com/resources/article_archive/results/details?id=3631 January 28, 2013 https://web.archive.org/web/20131104074540/http://www.hendonpub.com/resources/article_archive/results/details?id=3631 November 4, 2013 dead 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.
