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.[1] Projectiles are custom-made and most commonly weigh 3,600 grains (8.2 ounces, or over half a pound).[2]

[edit] Rifles
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 Title I rifle by a person over age 18 with no felonious criminal record. The rifles themselves, of which only a handful have been made, 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.[3] Despite the weight, recoil is significant, and shooters must be sure to choose components (i.e., scopes and bipods) that can handle the abuse. The sheer size and weight of these weapons makes them impractical for hunting use, as they cannot be carried afield. Thus, though impressive, they are largely "range queens"—rifles that are brought to the range for a fun time, but not usually used for hunting or other "more practical" uses. Additionally, the cost of owning and operating such a firearm is beyond most shooters; the rifles cost ~US$8,000, loaded cartridges are $40 each, and the individual lathe-turned bronze bullets are $10 apiece.[4]

[edit] Ballistics
The .950 JDJ has become something of an internet legend, and is frequently cited as an example of a "ridiculously large" cartridge, thanks to its overwhelming ballistic figures. The cartridge drives its aforementioned 3,600 gr (230 g) bullet at approximately 2,200 ft/s (670 m/s). This yields a muzzle energy of 38,685 ft·lbf (52,450 J).[1] For comparison, the 5.56x45 cartridge, used in the M16 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 .950 JDJ produces a colossal amount of energy by comparison. In a 110 lb (50 kg) rifle, this will develop well over 200 ft·lbf (270 J) of free recoil energy if an efficient muzzle brake is not used. This is far beyond the shoulder-firing capacity of nearly all humans, even without considering the difficulty of shouldering such a heavy rifle. Shooting should be done with a heavy "lead sled" or similar shooting rest, and the rifle should not be held to the shoulder unless the shooter is prepared for severe recoil and possible injury. The rifle scope should have significant eye relief to avoid injuring the ocular orbit.

I don't think there is enough behind that heavy ass bullet to allow it penetrate anything useful to the military... not to mention, the rifle would have to be mounted or on a sled. Like i said, it doesn't have anything on the 20mm as far as penetration. I think its was designed for rhinos and elephants or maybe a 7th grade science experiment

So.........that's were all the 5.56MM, 9MM, .380 and others brass have been going and causing the prices to go higher. If that round was recycled how many 9MM or .380 cases could be made from it?

I agree with reaper

It don't look like enough brass behind that thing to get it moving too fast. I know I don't want to be in the way to feel it though. Holy shit!
