world's largest and most powerful rifle cartridge

its a 950 JDJ Rifle Cartige. world's largest and most powerful rifle cartridge. but Not shoulder-fired The .950 JDJ is a large caliber rifle cartridge developed by J. D. Jones of SSK Industries.
950 JDJ cartridges are approximately the length of an empty .50 BMG casing (i.e., 4 in/10 cm), and are based on a 20×102mm case shortened and necked up to accept the .950 in (24.1 mm) bullet. Projectiles are custom-made and most commonly weigh 3,600 grains (230 g) which is 8.2 ounces or over half a pound.

As its name implies, rifles chambered for the cartridge have a bore diameter of 0.950 in (24.1 mm)
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 from 85 to 110 pounds (39 to 50 kg) and are therefore only useful for shooting from a bench rest or heavy bipod. Despite the weight, recoil is significant, and shooters must be sure to choose components (i.e., scopes ) 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, 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.

Ballistics.

The cartridge propels its 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)and a momentum of 154.1 Newton-seconds, about the same as a 20x102mm Vulcan round. This kinetic energy would allow the .950 JDJ to pass through several body-armored humans. It is comparable to the original tank rounds of World War I in terms of ballistics.

By comparison, the 5.56×45mm NATO cartridge, used in the M16 rifle, produces between 1,200–1,300 ft·lbf (1,600–1,800 J), while the .308 Winchester, a favorite for hunters and medium-range police/military sniping, produces between 2,000–3,000 ft·lbf (2,700–4,100 J) depending on the load used. The ballistics of the .950 JDJ is more similar to that of the 20mm autocannon round, which delivers approximately 39,500 ft·lbf (53,600 J). The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 lb (1,300 kg) automobile traveling at 20 mph (32 km/h).
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 is usually heavy "lead sled" or similar shooting rest, and the rifle is not held to the shoulder because of the severe recoil and possible injury. The rifle scope has significant eye relief to avoid injuring the ocular orbit.Parent case of 950 JDJ are 20 × 102 mm Vulcan and the Bullet diameter 0.950 in (24.1mm)Case length 4 in (100 mm)Bullet weight 3,600 gr (233 g) velocity are 2,200 ft/s (670 m/s)and ebergy produced 2,200 ft/s (670 m/s)

Have you seen the YouTube video of the guys firing it?



I'd love to use that as my CC weapon

Thank you tango charlie, real eye popping information. Can you please give details of trajectory and range,apart from entertainment, exhibition purposes what else this mini canon can be used for? Just that iam feeling curious.
