.476 Nitro Express

The .476 Nitro Express is a British rifle cartridge.

Introduced by Westley Richards around 1907, it follows on the heels of the .470, .475, and .475 No. 2 Nitro Express rounds. While it was available in single and double rifles, it was less popular than other comparable rounds. It is nearly identical in performance to a number of others in the same class.

The .476 is considered adequate for all African and Indian big game, including elephant and rhinoceros. Its ballistics resemble the .458 Winchester Magnum, with a larger diameter bullet; whether this is an advantage remains in dispute.

Commercial rifles are no longer available in .476 Nitro Express except by special order, ammunition is no longer commercially available, and handloading data are scant. The factory load used 75 gr (4.86 g) of cordite under a 520 gr (33.7 g) slug.
