    AR500 in .500 Auto Mag

    Want....just because.

    http://www.thefirearmblog.com/blog/2...kly+Newsletter 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. I have reached out to BHA for more details on the manufacturing status and projected availability of the cartridge itself. This article will be updated when that information becomes available.
    Per Big Horn Armory:
    Price: $1999.00

      The 50 Beowulf uses AR 15 type magazines so you can put it on a standard platform, fun round, but better suited for the reloader. I have one since the Alexander Bros came out with it, mine has been on a couple of hog hunts and does very well.

          I'm really confused. in what world is "a rimless 500 S&W Magnum" "capable of putting 50 BMG power"?

          Vaminos is all you need to say, we're gonna move eventually
          Pull the suckers off of one row, then turn around and do it again -

                Well shit, with 50 trigger pulls I can achieve that power with a .22 for pretty much the same price lol
