Monster .950 JDJ Cartridge with 3600gr Bullet Dwarfs a .50 BMG
Are you bored with your “whimpy” .50 BMG? Looking for something with a little more punch? Well J.D. Jones and his team at SSK Industries have created a truly big boomer — the .950 JDJ. As its name implies, rifles chambered for the cartridge have a bore diameter of 0.950″ (24.13 mm). This would normally make such rifles “destructive devices” under the 1934 National Firearms Act (NFA). However, SSK obtained a “Sporting Use” exemption allowing the rifles to be sold without special restrictions as destructive devices. CLICK HERE to watch .950 JDJ being fired.
.950 JDJ Specifications
Rifle Cost: $8000.00
Ammunition Cost: $40.00 per round
Projectile Weight: 3,600 grains (more than half a pound)
Rifle Weight: Between 80 and 120 pounds
Muzzle Energy: 38,685 ft/lbs (52,450 Joules)
Momentum: 154.1 Newton-seconds
As crafted by SSK Industries, .950 JDJ rifles use McMillan stocks and very large-diameter Krieger barrels fitted with a massive 18.2-lb muzzle brakes. The ammo produced by SSK features solid 3,600 grain bullets and CNC-machined cartridge brass. It is also possible (through a lot of work), to use a 20mm cannon casing shortened and necked-down.The primer pocket is swaged out to accept a .50 cal machine gun primer. That 3,600 grain bullet is just massive — it weighs more than half a pound. The cartridge propels its 3,600 grain bullet at approximately 2,200 fps. This yields a muzzle energy of 38,685 ft-lbs and a momentum of 154.1 Newton-seconds. The energy on target (knock-down power) is comparable to WWI-era tank rounds.

Let me guess – – the “sporting use” was squirrel hunting?
haha…wow, what can ya say! Even at $40 a round you get a lot of bang for the buck.
One could probably lower ammo cost by reloading… ;o)
Just remember only 0.002 shoulder bump to extend case life…
Is there a tight neck version?
Ok I`ve seen news of this BIG boy here and elsewhere. So far NO mention of any kind of accuracy. Big is cool but can ya hit anything with it..?
There’s an even bigger round called the 1.00 MR built by my friend Marco Rigido that is a full 1.00 inch rifle based on a 30mm aircraft cannon case. it has a higher muzzle energy than the 950 JDJ and can even be loaded to higher energy levels, but would be nearly impossible to shoot off the shoulder.
