The .475 No. 2 Nitro Express is a British rifle cartridge developed by Eley Brothers in the early 20th century.
Development
The .475 No 2 Nitro Express is one of several rounds (including the .500/465 Nitro Express, .470 Nitro Express, .475 Nitro Express, and .476 Nitro Express) developed as a replacement for the .450 Nitro Express following the British Army 1907 ban of .450 caliber ammunition into India and the Sudan, all with comparable performance.[1]
Eley developed the .475 No 2 Nitro Express by necking up their earlier .450 No 2 Nitro Express,[2] while W.J. Jeffery & Co chambered a slightly less powerful loading in their rifles.
Design & performance
The .475 No 2 Nitro Express is a rimmed cartridge designed for use in single-shot and double rifles. A good general purpose round, it is suitable for all big game, its power is almost identical to the .458 Winchester Magnum, with a larger diameter bullet; whether this is an advantage remains in dispute.[1]
The standard factory load used a 480 gr (31.1 g) slug over 85 gr (5.51 g) of cordite, the Jeffery loading used a 500 gr (32.4 g) bullet which dropped 0.6 in (15 mm) more at 200 yd (180 m).[1]
