The McBros .95 caliber rifle




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).

.950 JDJ cartridge wiki – HERE

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.

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.

When did breaking your shoulder become a “sporting use exception”???

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 ?

nathan November 11, 2011 at 02:23 pm

good news someone made a semi auto for the round and it will be in a beafed up ar style gun in two months

Jeremy November 28, 2011 at 02:55 pm

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.

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)

That’s an insane gun why would you need a gun like that in the first place

Victor April 18, 2013 at 07:24 am

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…

James April 25, 2014 at 09:27 pm

What is the maximum effective range of the .950? I’ve looked up pretty much every available source and I can’t locate one.
