    Default .50 Beowulf?

    I'd been planning to do a .50 Beowulf AK with a bent receiver, but a milled Chinese receiver is now laying on my workbench. It's part of some kind of training/DEWATS rifle; the barrel is welded up, the top cover has a few short (and pretty!) TIG welds anchoring it to the receiver, and it's missing the bolt and carrier.

    I'll need the following:

    .50 barrel

    7.62x39 bolt to match the Beowulf case head

    bolt carrier and operating rod

    .223 magazine (may require some "adjustment" according to the AR15 sites)

    modified or full-custom RSB, gas block, and FSB - the .50 barrel would have to be thinned unworkably to match the OEM bits. Though machining them from scratch is okay, I might cheat, saw the rings off, and weld or silver solder them to appropriate-sized tubes

    At the moment, the only real point of uncertainty is the barrel attachment - it appears to be threaded into the receiver. I know I saw a chart around somewhere that gave the thread specs, but darned if I can find it now...

    Anyone see anything major I've overlooked? Other than the gas and sight blocks, it looks fairly easy.

    Sounds like you have a good plan with the parts. The use of a larger diameter ring will probably be required if the enlarged gas block is thin enough to fail from the stresses of the gas pressure.

    Meeper (on FALFILES) did this caliber a few years ago based on a SAR.

    I can't find a pin, so I'm assuming the barrel is threaded. Personally, I like the pressed barrel idea. If the chamber diameter looks iffy for the original threads, I'll probably open it up for a pressed barrel and drill for a pin.

    > have you considerd a AR mag addapter so you can use AR

    No, I didn't think of that. What it is, a sheet metal magwell I could weld to the AK receiver?

    > persoanly I like the 450 bushmater or the 458 socom
    > better.

    Back last summer I had decided to build a "brush gun" out of a 1917 Enfield I had on hand. Short barrel, big low-velocity cartridge I could use with cast bullets. I was searching Google on ".45-70" and "Enfield", and for some reason it returned Pookie's .45-70 AK thread here. After marveling that someone would be demented enough to do such a thing, I spent the next several months reading, acquired a Romy kit, made the bending and press jigs, etc. I've drunk the Kalashnikov Kool-Aid...

    Since I intend to cast my bullets, they're all the same price. Beowulf brass is about the same price as, or even slightly cheaper than, .45-70 brass. The best price I've found on a .50 barrel is about triple that of a .45-70. Can't win 'em all... after studying Pookie's magazine hassles, it looks like the Beowulf would be much easier since it uses a .223 magazine.

    I was reluctant to consider the Beowulf at first due to Alexander Arms' psycho-yuppie BS, but it's not like I'm dependent on them for a chambering reamer. If a .50AE reamer won't do, I'll either make one or send the barrel out and have it done on a CNC lathe. If the Beowulf doesn't become popular - frankly, I doubt it'll take off - a few gross of brass should do me for the forseeable future, or at least until the new wears off...

    Yeah its amazing some of the crap people think of doing!

    I'm really REALLY close to being able to spend some quality time on this one. Chamber reamer is on order. Finally.

    I'm with 1biggun, I think the 450 Bushmaster will be the most prevalent of the rounds because it has Bushmaster and Hornady driving it. The SOCOM coming in close behind it. If Alexander Arms would get off their keister and "release" the cartridge spec without the licensing BS then it would really take off. Too much greed is keeping that one grounded. I think they are holding out for military contracts, but frankly I just don't see it really taking off.

    Nice thing about the 450 brass is that it can be done up fairly easy since it is cut-down .284 brass (as I recall it is .284 but I am going from memory)

    Look on my topic about "intermediate 45 and 50 cartridges" for some other candidates. There is a .499 LWCS (again going from memory) that was designed by a spin-off of the Beowulf design team. It looks marginally stronger in performance than the Beowulf and may be worth consideration.

    This was a one-time deal - a friend's neighbor was moving and had it in his garage, something he apparently carried home from work. (military)

    > YOU GOT TO POST SOME PICTURES HERE. pLEASE.

    I'll do it soon. It's one butt-fugly item, though.

    > WHAT WAS THIS DUMMY GUN ORIGINALY????

    There are no importer markings, so I'm assuming it was captured and demilled. I'm not sure why, unless it was for "how to identify an AK-47". It's pretty beat up, but not the muzzle or buttplate, so it wasn't used for drill.

    > THE ADAPTER FITS JUST LIKE A REGULAR MAG AND THEN
    > THE AR 223 MAG FITS INSIDE THAT.

    Hm. I should invest in a .223 mag and see how much trouble it would be to modify the AK mags. I only need a few.

    I'm not really concerned with the OEM ballistics. I'll be handloading down to whatever the rifling is happy with before leading becomes an issue. I've read just about all the threads here, and I'd thought about doing a wildcat by cutting down a .30-06 to whatever was convenient, just as others had. However, Beowulf brass is cheap at the moment, and it has the "it's a .50" cachet.

    If I was loading for max ballistics things would be a lot different. I'm still thinking "brush gun".

    Someone needs to go stick a pitchfork in him...

    > GETTING A REAMER OR HAVING IT DONE WAS ABOUT
    > IMPOSSABLE BUT IT HAS BEEN DONE

    I'm willing to try making one. With a full-length barrel, I have the opportunity to make quite a few tries before getting into SBR-land... otherwise, I'll try cutting the chamber with a lathe.

    Granted, but there has already been at least one AK in Beowulf, a couple in S&W, and that .50-110. Not to say that there probably weren't hours of smoking the parts with candle soot and watching for shiny spots while working the action...

    I don't know what you mean, there. Can you point me to a picture?

    Here on gunco?

    > I WOULD WANT A ADJUSTABLE GAS BLOCK

    Don't we all... if I wind up building from scratch, it'll be adjustable to start with.

    > LEAD FOULING ON THE GAS PORT MIGHT BE A ISSUE AS
    > WELL.

    I'll burn that bridge when I get to it. I have a sketch for a gas block with a cleaning port, but I'm betting it won't be a problem.

    > i AM NOT TRYING TO POO POO YOUR BUILD UST
    > POINTING OUT SOME THOUGHTS

    That's what I asked for, and I appreciate your input.

    I don't think a .50 AE reamer would work. From Wikipedia:

    Beowulf neck: .525"
    Beowulf base: .535"

    AE neck: .540"
    AE base: .547"
