I pass this one along for your edification. According to the text that came with the video, this is one of three .950 JDJ rifles made by SSK Industries of Ohio. This is the lightest of the trio, the carbine version, weighing in at a negligible 50 pounds. The bullets, which appear to be lathe-turned bronze, weigh 2,400 grains and are pushed at 2,100 fps by 240 grains of powder. The .950 JDJ develops 25,400 foot pounds of muzzle energy and 277 foot-pounds of recoil.
