The SSK Industries .950 JDJ – The Largest Centerfire Rifle Ever Made

The .950 JDJ is the largest centerfire rifle ever made, built by SSK Industries of Ohio. Weighing in at 50 lbs., the rifle featured in the video is only the prototype variant, one of three total rifles built; the other two weigh in at 110 lbs. The JDJ fires a .95 caliber 2400 grain bullet at 2100 fps using 240 grains of powder, which generates 25,400 ft/lbs of muzzle energy and 277 ft/lbs of recoil energy.

Simply put, it’s extremely heavy, kicks like a mule, you’d be paying $40/cartridge, and you know you want one.

    Most powerful, probably. The largest, nope. It is surpassed by the 4-bore and 2-bore rifles from the late 1800s African hunting period. The 2-bores clocked in with a 1.326″ half pound bullet (3,500 grain brass solid) moving out at 1,500 ft/s (producing 17,500 ft/lbs of energy). The recoil from the 20+ pound shoulder fired rifle was reported to be fierce (probably an understatement).

      Not even the most powerful.
      There is Finish Lahti L-39, Japanese Type 97, Swiss Solothurn S-18, Croatian RT-20, South African Mechem NTW-20, and so on.
      And if you want to go further back in history, there is fortress gun Krnka-Gan 1876.

    Anybody know the effective range?

    I feel that such a round would probably need more than a bolt action platform to shoot from, probably a rifle with hydraulic dampers or something.

    This is the biggest (produces the most foot pounds) sporting cartridge allowed by law. Meaning you do not need to pay the $200 dollar stamp tax for a “destructive device” despite having a bore diameter over 0.501. The law excempts certain cartridgies from being DDs, this is why the “sporting cartridge” designation is important.

    An old analogy comes to mind…..Just because you can, doesn’t mean you should.
