that has got to be one hard hitting AR. How is it on range, recoil? I'm not familiar with the caliber but whould like to learn more bout it.
The .50 Beowulf has been likened to a .45-70, and that's really not a bad analog for the .50 Beowulf, .450 Bushmaster or .458 SOCOM.
Some of the projectiles used were meant for the .50AE Desert Eagle, so the predictability of performance is spotty in some respects. The guns kick (to me) about like a 20ga shotgun.
The Beowulfs I've played with suffered with some mag/feed problems, whereas the .458 SOCOM uses standard unaltered AR mags. The .458SC also has the benefit of being able to use projectiles designed for the caliber, as well as those designed for use in the .45-70 and .458 Win Mag.
The practical range is limited by the significant drop of the projectiles used. The .50B and .458SC basically turn the AR into a 100yd or closer car-killer extraordinaire in my opinion. The .450BM is limited by the relatively light/expanding ammo loaded for it by Hornady (hunting stuff) and a low mag capacity.
