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,[1] including elephant and rhinoceros. Its ballistics resemble the .458 Winchester Magnum, with a larger diameter bullet; whether this is an advantage remains in dispute.[2]
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.[2] The factory load used 75 gr (4.86 g) of cordite over a 520 gr (33.7 g) slug.[2]
