The .700 WTF Cartridge – “WTF?” Indeed…

Capture

Aptly called a “hand cannon” in the video, JT Custom Knives has debuted video of the .700 WTF cartridge. The .700 “slugs” are 1132 grains (or about 1/6 lbs) loaded with “mid-level” shots at 1600 FPS. According to the video description, the free recoil without a muzzle brake is around 150 ft/lbs.

    Although still really cool, this was covered by TFB a couple of years ago.
    Are there any updates? Has he started manufacturing and selling this cannon?

    • Hans

      It’s been covered several times actually, each time with pretty much the same info.

  • More information would be nice.

    Is this just a fun project? Or are they serious about producing it?

    Did they register it as a DD, or are they going for a “Sporting Purposes” exemption?

  • Matrix3692

    looks like it could use a high-B.C. bullet……like a 100mm long bullet

  • John Bear Ross

    Very cool. Just like Ed Hubel’s 12 Gauge From Hell.

    Best,

    2 complete sets of locking lugs on that bolt… awesome.

  • Zebra Dun

    Useful in a manhood test.

    I’m all for the .700 WTF, FTW !!

  • DIR911911 .

    .700wtf or as it’s commonly known . . . the bus stopper.

  • Swampthing

    Maybe when we have powered exoskeletons, guys will be running semi auto versions of this lol.

    • Adam

      Oh you think thats funny….A Semi is already in the works…

  • Lance

    Now that’s one heck of a GUN!!!

  • Cal.Bar

    Why is this referred to as a “hand cannon” when it very clearly seems to be only fired with a shoulder stock like any large bore rifle. When we see it fired with two hands and no shoulder THEN we can call it a “hand cannon”.

    • Darren Hruska

      By ATF logic, it needs to be fired with one hand to be a handgun. Otherwise, potential “repurpose.” ;3

  • hcpookie

    Looks like a “short” 12 GFH round… which can nearly double that velocity 🙂

  • Cymond

    I wonder if he actually bothered to get a sporting exception, or if he just assumed that the ATF would grant one, like some people do.

  • Giolli Joker

    Now I feel old. 🙁

    • Adam

      Dont worry, this is my other project.. Prototyping the rifle now, just waiting on a die set,,I will have properly head stamped brass, or just make it from once fired BMG brass…

      • Giolli Joker

        So, you’re the guy behind the WTF?
        Keep us posted!!! 🙂

        • Adam

          No, i started pestering Jason when he first built the dam thing.. Its a cheap 700 Nitro Express.. He just never built them… So two years ago, I ordered rifling buttons, gun drills and pull through reamers, And all the tooling i needed to make the rifle and barrels.. Im still waiting on the reloading dies and the bullet swage dies. I will post you pics once the two prototypes are done.

          • Giolli Joker

            OK!!!

  • Mr Evilwrench

    The .950JDJ makes it look small.

  • Adam

    I loved the idea so much, I decided to start building them….. (insert Evil laugh)

  • Michel_T

    Bump it up to a 787 WTF… then we’ll be able to make a subsonic 20mm 😉
