Bill Alexander, of Alexander Arms, was one of the pioneers of big-game hunting cartridges in the AR-15-style rifles. He developed this cartridge and named it after Beowulf, a legendary literary warrior who slayed the invincible Grendel by ripping his arm off. The day after that battle, Beowulf fought the monster that was Grendel’s mother and killed her by cutting off her head with a mighty sword from her own armory; a sword of which it was said, “no other man could have hefted in battle.” Years later, when he was an old man on the decline and but a shell of his former self, Beowulf fought and killed a dragon.
The .50 Beowulf was introduced in 2001 and was the first of the big-bore cartridges designed for the AR-15. The cartridge is based on a lengthened .50 AE case with a severely rebated rim so it fits a bolt head designed for the 7.62×39 mm cartridge. Bullets are .500-inch, the same as the .500 S&W Mag.,
The .50 Beowulf bullet is half-inch in diameter and can expand to more than an inch. Compare that to a 55-grain .223 Rem. at .224-inch. The 300-grain Beowulf has 627 percent more bullet weight and an unexpanded diameter that is larger than a .223’s fully expanded bullet. Expanded, the Beowulf bullet has a 123-percent larger frontal diameter than the .223’s expanded bullet. The Beowulf has almost three times as much muzzle energy as the .223 Rem. and more than four and a half times the momentum. This is a serious step up in power for the AR-15 platform.
