Gun Pr0n: the most powerful rifle in the world

Ladies and gentlemen, the .557 Tyrannosaur.

This rifle is made by A-Square, Inc. based upon their Hannibal rifle platform, and it fires a .557 cal. cartridge. The 750 grain Barnes Solid Projectile moves at 2,460 feet/second, generating over 10,180 foot-pounds of energy (just for comparison, a .44 Magnum firing a 240 grain bullet generates approximately 1,180 fps. of muzzle energy). And 10 rounds for this beast will set you back about $150.

From the looks of this video, it'll set you back a bit more than that...
