The rifle bullet that makes the .50 Cal look like a pussy:

.950 JDJ

The .950 JDJ has become something of an internet legend, and is frequently cited as an example of a "ridiculously large" cartridge, thanks to its overwhelming ballistic figures. The cartridge drives its aforementioned 3,600 gr (230 g) bullet at approximately 2,200 ft/s (670 m/s). This yields a muzzle energy of 38,685 ft·lbf (52,450 J).[1] For comparison, the 5.56x45 cartridge, used in the M16 rifle, produces approximately 1,200–1,300 ft·lbf. The .308 Winchester, a favorite for hunters and medium-range police/military sniping, produces between 2,000 and 3,000 ft·lbf (4,100 J) depending on the load used. The .950 JDJ produces a colossal amount of energy by comparison. In a 110 lb (50 kg) rifle, this will develop well over 200 ft·lbf (270 J) of free recoil energy if an efficient muzzle brake is not used. This is far beyond the shoulder-firing capacity of nearly all humans, even without considering the difficulty of shouldering such a heavy rifle. Shooting should be done with a heavy "lead sled" or similar shooting rest, and the rifle should not be held to the shoulder unless the shooter is prepared for severe recoil and possible injury. The rifle scope should have significant eye relief to avoid injuring the ocular orbit.

For comparison, Burt's anti-tank rifle on the second Tremors film was a mere 20-mm shell. The JDJ's around 24-mm thick. Forget blowing a hole in human targets - this'll turn the torso into meat sauce.
