    Default .50 Beowulf or .458 Socom AR

    Thinking about building a .50 Beowulf or .458 Socom AR. Any one every put one of these together? Is there an advantage to one or the other? Any tips, tricks or advice would be greatly appreciated.

    No, but that sounds awesome! Looking forward to seeing this come together...I think KMM696 may be building a SOCOM, so perhaps he'll chime in...

    I believe Fooped has a .50 Beowulf... I think it was his that I shot at the last car shoot.

    I've never heard of .458 SOCOM, so I looked it up. It's got some interesting ballistics.

    2405 ft/lbs on 300 gr at 1900ft/s
    2664 ft/lbs on 600 gr at 1000ft/s!

    Over a ft-ton of energy from a subsonic round!

    I imagine you would have to reload, I've never seen .458 on the shelves.

    Just east of Zone 9, but in Worcester County.



    That was my .50 Beowulf. (^_^)

    Can't comment on which one would be a better choice. BOTH are exceptionally difficult to find ammo for right now. Even brass is a royal PIA.

    Don't know much about the SOCOM loading, so I can't comment on it. If you search, you'll find a few posts I've made on the Beowulf loads.

    This one was probably the most info packed about the round.

    Eye Candy:

    A clip is not a magazine, a mag is not a clip.
    Neither is a grip a stock, and "stock" does not mean grip.
    A bullet is not a cartridge, nor is the converse true.
    Folks should be more careful when they use the words they do.
    A revolver has a cylinder, but only one you see,
    and cylinders have chambers, five or six most commonly.
    I do not wish to nitpick, but improvement would be seen,
    if we could bring ourselves to say exactly what we mean.

    Fooped's AR is in 50 AE, I believe. I'm dying to get to the range with it and him - Apparently it packs QUITE the punch

    Yup, mine is in .50ae, and makes a significant bang. Uncle Fester has a .458 Socom AR PISTOL.

    Yup, you read that right.

    It's every bit as unwieldly and insane as that sounds.

    458 socom takes standard unmodified AR magazines. The others require modifications. So if you already have a pile of AR mags, you won't need to buy more or modify them.

    I have no experience with 458 Socom, but I do own a 50 Beo. The 50 Beo is quite a beast and will do wonders for your shoulder .

    Finding brass and loaded ammo is tough, but bullets and powder are pretty easy to find.

    This isn't correct. There are plenty of people out there using preban 20 and 30 AR round mags (if your in MA) in unmodified condition. The feed lips on a Beo mag are barely noticeable. The only real difference is the color of the follower and the plate.

    Have you considered the 6.5 Grendel?
