.577 Tyrannosaur

The .577 Tyrannosaur or .577 T-Rex (14.9×76mm) is a very large and powerful rifle cartridge developed by A-Square in 1993 on request for professional guides in Zimbabwe who escort clients hunting dangerous game. The cartridge is designed for use in "stopping rifles" intended to stop the charge of dangerous game. The cartridge contains a .585-inch (14.9 mm) diameter 750-grain (49 g) monolithic solid projectile which when fired moves at 2,460 ft/s (750 m/s) producing 10,180 foot-pounds force (13,800 J) of muzzle energy. The production model from A-square was based on their Hannibal rifle. A-Square is defunct as of 2012.
