Manufactured by SSK Industries, this enormous rifle pushes the envelope in size, raw power, and rarity. This rifle is designed to fire a cartridge based on the 20x110mm Vulcan Cannon cartridge, shortened, and necked up to match a .950 caliber (24.1mm) cast lead bullet. The round is large enough that when developed by J.D. Jones of SSK industries, they had to receive a "Sporting Use Exception" from the ATF to deregulate the rifles. SSK Industries manufactured only three of these rifles, and as of 2014 SSK no long produced ammunition for it. Manufactured without sight, on the super heavyweight Krieger barrel, enormous eight chamber muzzle brake, and fitted with a Burris 7x scope. The barrel is marked "SSK 950 JDJ Gun Number One" in fancy script lettering on the left side. The action functions by removing the bolt from the receiver, placing the round directly into the bolt, and putting the whole assembly back into the receiver, similar to how anti-tank rifles are loaded. The rifle weighs an astounding scale-breaking 61 pounds! Mounted on a McMillan style extra large benchrest style stock with a solid recoil pad. Includes two reloading dies, approximately 23 loaded rounds, 63 empty casings, two wood loading blocks, and approximately 90 cast lead bullets.

Excellent. 97% original polished blue finish remains with some scattered light pitting visible on the barrel and handling marks overall. The stock has a few areas of wear mostly confined to the underside, and grip areas. Mechanically excellent. The scope is excellent. This is the largest and heaviest sporting rifle writer has ever seen, and an impressive testament to the gunsmithing arts.
