.50 Beowulf
The .50 Beowulf is a rifle cartridge developed by Bill Alexander of Alexander Arms for use in a modified AR-15 rifle. ==Design and specifications== The cartridge utilizes a rebated rim, sized to match the rim of the 7.62×39mm and 6.5 mm 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.
