The SSK .950 JDJ is an absolute beast. Made by SSK Industries, each bullet is over four inches long, weighs over half a pound and costs about $40. There are only three rifles ever made that can fire the round. The weapons weigh between 85 and 120 pounds and produce a recoil capable of injuring its shooter.
"The JDJ is comparable to a World War I-era tank round or a 20mm cannon in terms of kinetic energy," according to Weekly World News.
The weapon's sheer size and power make it impractical for hunting, so don't expect to see this monster anywhere besides the range.
