.600 N.E.

The .600 Nitro Express (N.E.) is a large-caliber, dangerous game hunting cartridge designed for use on the largest and most dangerous game in Africa and India. It was introduced in the early 20th century by W.J. Jeffery & Co., a British gunmaker.

The .600 N.E. uses a .620-inch diameter bullet and has a case length of 3.25 inches. It is loaded to produce muzzle velocities of around 1,850 feet per second and can deliver muzzle energies in excess of 9,000 foot-pounds. The cartridge is known for its significant recoil and is typically used in double rifles or single-shot rifles.

The .600 N.E. has been used to hunt a variety of large game, including elephants, cape buffalo, and rhinoceroses. However, due to its high cost, recoil, and the limited availability of firearms chambered for the cartridge, it is not as widely used as some other cartridges such as the .458 Lott or .375 H&H Magnum.

Today, the .600 N.E. is primarily used by hunters who specialize in hunting the largest and most dangerous game, as well as by collectors and enthusiasts of big-bore hunting rifles.
