The .950 JDJ is among the world’s most-powerful, and largest-caliber, rifle cartridges. Loaded .950 JDJ cartridges are approximately the length of an empty .50 BMG casing (i.e., 4″), and are based on a 20mm Vulcan case shortened and necked up to accept the .950″ bullet. Projectiles are custom-made and most commonly weigh 3,600 grains (8.2 ounces, or over half a pound).

As its name implies, rifles chambered for the cartridge have a bore diameter of 0.950″, which would normally classify them as Destructive Devices under the 1934 National Firearms Act. However, SSK sought and received a “Sporting Use Exception” to de-regulate the rifles, meaning they can be purchased like any other rifle by a person over age 18 with no felonious criminal record. The rifles themselves use McMillan stocks and extraordinarily thick Krieger barrels bearing an 18 lb (8.2 kg) muzzle brake. Overall, depending on options, the rifles weigh between 80 and 110 pounds and are therefore only useful for shooting from a bench rest or heavy bipod. Despite the weight, recoil is significant. muzzle energy of 38,685 ft·lbf (52,450 J). For comparison, the 5.56×45 cartridge, used in the AR-15 rifle, produces approximately 1,200–1,300 ft·lbf. The .308 Winchester, a favorite for hunters and medium-range police/military sniping, produces between 2,000 and 3,000 ft·lbf (4,100 J) depending on the load used. The rifles cost $8,000, loaded cartridges are $40 each.
I can’t believe the muzzle energy on that thing… that is NUTS.
As cool as this is, I much would rather have a .50 caliber Barrett for so many reasons.

Hi,
You guys really need to take a short video of this thing being fired and put it on you tube. I’ve been searching and this is the biggest gun i’ve come across on the internet. A close second is the Anzio Ironworks 20mm that you probably know of. If, however, yours is necked up then the public really deserves to see this thing in action. Great looking gun, I love it.
Regards
That thing’s fucking mental.
When did breaking your shoulder become a “sporting use exception”???
SON. OF. A. BITCH!
That thing kills on one end and maims on the other!
I honestly don’t know if I could talk myself into pulling the trigger. Not without some sort of anchoring system. That thing would have the recoil of a small horse. What is the use of this gun anyway? I can’t thing of what it would be useful for other than shock value or a case of ” I have the biggest….”
Hey, im pretty, but the gun has a hole in the hand guard to mount it on a truck/tripod. forgot the site I saw the video on, but the gun was mounted on an older model truck and when he shot the gun the truck swayed about a foot left to right. It was amazing.
Thats the definition of one shot one kill.
How much for one of these ?
good news someone made a semi auto for the round and it will be in a beafed up ar style gun in two months
To answere the questions, there is a video of a guy shooting on on youtube that is from a christian band and his chair scoots quite a bit, they cost about 8000 dollers us and sks the inventers of the round say it would cost no less then 5000 on their website. though about all they would be good for would be range shooting, or where you would hunt from a fixed location, like peirey dog hunting.
Though I guess on the sks website they say it has a 1.5 inch grouping at 500 yards for the one they will build if you want one.
Jesus… Thats Insane!
Absolutely not reason for something like. I dont even want to know what the recoil is like… Dislocated shoulder anyone?
Just snuggle up to shoulder…HOLD FIRM and squeeze trigger …Then get back up and say WHOO..WHHHOO No More….BYEEEEEEEEEEEEEE
BOW DOWN MAGIC S–T !!!!!!
PJ
I’ll shoot this gun at any range that will let me for 100 dollars a shot. just to prove it wont kill the shooter… (the 100 dollars is just to cover my accidental death insurance)
Hmmmm… Well i was having this dinosaur problem the other day
was it a T-REX
Was the dinosaur your mom.
That’s an insane gun why would you need a gun like that in the first place
Well, If dudes had these attached to a jeep in Jurassic Park, the T-Rex and Spinosaurus would have no chance, as well as Anaconda, Gremlins, Vampires or the Devil…
What is the maximum effective range of the .950? I’ve looked up pretty much every available source and I can’t locate one.
Seriously painful experience:
