Shooting 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 1 round for this beast will set you back about $40.
