Development
Development
The.476 Nitro Express is one of several rounds (including the.500/465 Nitro Express,.470 Nitro Express,.475 Nitro Express, and.475 No. 2 Nitro Express) developed as a replacement for the.450 Nitro Express following the British Army 1907 ban of.450 caliber ammunition in India and the Sudan, all with comparable performance. Westley Richards created the.476 Nitro Express by necking down the.500 Nitro Express 3".
Use
Use
Available in single-shot and double rifles, it was less popular than the above-mentioned 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.
