.950 JDJ – Largest Center-Fire Rifle Ever Made. This gun is larger than a .50 cal and larger than the famed T-Rex
The round is .95 inches in diameter, and weighs a staggering 3600 grains (8 ounces, half a pound).
The rifle is a single-shot bolt action rifle, weighing about 110 pounds, 18 of which is the muzzle brake.
The bullet has a muzzle velocity of 2,200 feet per second, and generates 38,685 lbs/ft of energy. It also generates a recoil impulse of 200 lbs/ft, or about 13 times the recoil energy of a .308 Winchester. This recoil is FAR beyond the capability of most humans to tolerate, and can in fact cause severe or even fatal injuries. To compensate for this, the rifles are typically fired from a lead sled type shooting rest.The rifle costs about $17,000 by itself, and each round costs nearly $80.
