Got this from someone. Impressive!
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 f/lbs of muzzle energy and 277 f/lbs of recoil energy.
Each round costs $40.
