Overview of 50 Beowulf Ammo
.50 Beowulf is one of the largest cartridges that fits the AR-15 platform. It fires a .500-inch bullet, usually 300 to 400 grains, at around 1,800 to 1,900 fps. That delivers massive close-range energy for hogs, black bear, and deer in thick cover, as well as for vehicle and barrier work, with recoil similar to a 12 gauge slug.
50 Beowulf uses a rebated rim that matches the 7.62x39 bolt face and feeds from standard-size AR-15 magazines in single-stack fashion. For another big-bore AR-15 option, see our 450 Bushmaster ammo and 458 SOCOM ammo.

Frequently Asked Questions
What do I need to shoot 50 Beowulf in an AR-15?
You keep your AR-15 lower receiver and add a 50 Beowulf upper with its own barrel and bolt. Standard AR-15 magazines generally work, feeding the large cartridges in a single stack and holding fewer rounds.
50 Beowulf vs 450 Bushmaster: what is the difference?
50 Beowulf fires a heavier, larger-diameter bullet with more close-range energy. 450 Bushmaster shoots flatter and has much wider ammunition availability, and its straight-walled case is legal for deer in more straight-wall states. 450 Bushmaster is usually the better choice for longer shots.
Is 50 Beowulf good for hog hunting?
Yes. 50 Beowulf with a hollow point like Underwood 350gr XTP is a powerful hog and bear cartridge at close range, typically within 150 yards. Check your state's hunting regulations.
More About 50 Beowulf Ammo
Bill Alexander of Alexander Arms developed .50 Beowulf in 2001, the same designer behind 6.5 Grendel. The goal was a big-bore AR-15 cartridge that could stop vehicles at checkpoints and deliver extreme energy at close range from a standard rifle platform.
The name is a trademark of Alexander Arms, so similar ammunition from other makers is sometimes sold as 12.7x42mm. Today 50 Beowulf has a loyal following among hog hunters and shooters who want the biggest bore an AR-15 can handle.
