Big Horn Armory’s new project: The AR500 in .500 Auto Mag

Something new is coming next year from Big Horn Armory:  The AR500 in .500 Auto Mag.  Billed as “the most powerful short range semi-auto in the world”, the ballistics on the new cartridge are most impressive if confirmed. Out of an 18″ barrel, numbers for some of Underwood’s and Doubletap’s loads well exceed ME for the .458 SOCOM and even Brenneke Black Magic Magnum Slugs.  These massive rounds aren’t so slow, either.  Many are moving along at over 2200 fps, not bad for 350-400gr bullets.  For comparison, this somewhat comparable to .458 Win. Mag/375 H&H Mag-level performance at short range.

The diameter and OAL of the cartridge requires it to be chambered in a AR10-based platform, so this power comes with a premium in size and possibly weight over big-bore platforms compatible with AR15 lowers.  Magazines that ship with the rifle with hold 10 rounds.  At first glance, the new rifle and cartridge do not appear to use a “compact” AR10 lower. No word yet on whether we will ever see a massive semiauto handgun chambered in this round.  Per Big Horn Armory:

Price: $1999.00

Introducing the Big Horn Armory AR500 semi-auto rifle. Chambered in the 500 Auto Mag cartridge. It is the most powerful short range semi-auto in the world. Based on an AR 308 platform, it is capable of putting 50 BMG power on target with three trigger pulls with very reliable extraction.
