The 50 Beowulf suppressor friendly cartridge utilizes a rebated rim, sized to match the rim of the 7.62×39mm. 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 .50 Beowulf suppressor friendly round is intended to improve stopping power greatly at short- to medium-range as compared to the standard 5.56×45mm NATO round.

With normal bullet weights between 300 and 400 grains, 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 suppressor friendly cartridge is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of early .45-70 Government rounds as well as a perfect candidate for suppressors.

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, including deer, moose, and black bear.
