Got $40? Meet the .950 JDJ

Wanna launch a 1/2-pound bullet at 2300 feet per second? It’s gonna cost you ($40 per round) and it’s gonna hurt. It may break your ribs when you fire it, but the .950 JDJ has one advantage over other cartridges in the 20mm antiaircraft category: it has an almost-unique ATFE ‘sporting use exception’ which allows you to own it without jumping through the burning hoops of fire completing NFA paperwork required for ‘Destructive Devices.’ All right Mr. DeMille, I’m ready for my close-up . . .

I met a custom ammunition maker who’s willing to do the milling and lathing required to load up these beasts. Here I am posing with a [thankfully inert] display cartridge. And I am big; it’s the bullets that got bigger!

    My friend Marco Rigido of New System Arms in Italy builds a bigger rifle – a full 1.00″ bolt gun firing 2500 to 2800 gr bullets. Not sure if they can be imported here. From what I understand the SSK round is allowed for civilian use by the ATF. The Rigido rifles are legal in Italy, though.

    No thanks, much rather meet booth babes….

  3. avatar Joe Grine says:

    No interest.

    I’d squeeze off a few.

  5. avatar shazbot says:

    I was always under the impression that a gun was something that only dished out pain at one end.

    “Sporting Use”????
    For what? Hunting armored cars?

    1. avatar ROger.45 says:

      More like locomotives!

    2. avatar Mr. Lion says:

      Well, eventually deer might learn to hide behind trees. Really old trees.

  7. avatar Gerard says:

    They must have a heck of a scope and mount.

  8. avatar Kevin T says:

    if i had one it would be in an artillery set up not going into my shoulder. just have an anti car gun. legit.

    I think that even the ATFE finally realized that an 80-pound, handbuilt, $8,000 single-shot rifle with handmade ammo that costs $40 per round is probably *not* going to be of any use to a criminal. It would take two or three of them to lift it.

    Common sense, from the ATFE: who’da thunk it?

    1. avatar crstnhhn says:

      I have been a firm believer that – “Common Sense”, and – “Government” – isn’t synonymous! lol

    Ready for dinosaurs.

  11. avatar GG says:

    Damn, that is light artillery with a stock.

  12. avatar Chaz says:

    Power factor = 8050; definitely makes major… ;->

    For when you only get one shot to stop a bear.

  15. avatar Thomas Lane says:

    How soon before Smith and Wesson builds a 3 shot revolver for it?

    1. avatar Brian Kingston says:

      Haha!! I like your way of thinking!!

  16. avatar Redneck says:

    It would be very interesting to see the results of that shot (assuming they hit). Gotta figure not much in the way if petitioning, would love to see penetration through a row of…..whatever really….

  17. avatar Jim says:

    If they make a hollow point it could be a nice place to store car keys or cuff links, maybe a dog bowl for an old hound with arthritis. This weapon has little practical purpose, but what a toy. Would I be missing the point if I asked for a suppressor so I didn’t annoy the neighbors if I was “plinking” in the garden?

  18. avatar John says:

    where might one acquire one of these beasts?

    1. from what i hear there where only a few make by sks but you can still find some costom made for around $17,000. if only i had added a 0 by mistake……

  19. avatar Kevin says:

    I really want to buy one of these rounds, but don’t know where to get em.I want it inert so i don’t blow myself up & knock down a few buildings.

  20. avatar Butch says:

    Would be great to stop a run away train.

  21. avatar P. Ireland says:

    I am interested in purchasing a single .950 round, preferably live but would consider an accurate replica, for a friend who is an avid ammo collector. Previous posts listing such shells are a year old. Does anyone know of any recent sources for this monstrous round?

    1. avatar Ryan says:

      They’re closer to $95 shipped for a live round (I know because I have one). Contact Mr. Jones from SSK Industries and ask if he’ll make a live round for you. He did so for me late June of 2011.

  22. avatar Charles Hanks says:

    actually would just use a 600 nitro Express rifle…will stop anything pretty much. kills elephants with one shot.. hippos too. still kicks like a mule but still a stopper from old times that make it relevant still today.
