Sorry if this has been posted before... .950 CALIBER RIFLE Put aside your girly-man .458 Win Mag or your wimpy .50 cal and watch guys shoot a real gun, the largest center fire rifle ever made, the .950 JDJ by SSK Industries (Ohio). Only three were ever made. This was the lightest, the carbine version, weighing in at 50 lbs. It shoots a .95 caliber 2,400 grain bullet at 2,100 fps using 240 grains of powder, which generates 25,400 ft/lbs of muzzle energy and 277 ft/lbs of recoil energy. Each round costs $40.
