What is 577 tyrannosaur?

The 577 Tyrannosaur is a powerful rifle cartridge developed by A-Square Company in the late 1990s. It is one of the most powerful commercial rifle cartridges in the world, designed for use in hunting large and dangerous game such as elephants, rhinoceros, and large predators.

The 577 Tyrannosaur cartridge is based on the .585 Nyati cartridge case but necked down to accept .577-inch bullets. It fires a 750-grain bullet at a velocity of around 2,460 feet per second, producing tremendous stopping power and penetration at long ranges.

The 577 Tyrannosaur is typically used in single-shot rifles with heavy barrels and strong actions, as the recoil generated by the cartridge is very powerful. It is considered by many to be overkill for most hunting applications, but is favored by some big game hunters for its sheer stopping power and ability to take down large and dangerous animals with a single shot.

Overall, the 577 Tyrannosaur is a specialized and extremely powerful cartridge designed for those who require maximum stopping power in a rifle cartridge.
