The .475 No 2 Nitro Express is a British rifle cartridge developed by Eley Brothers in the early 20th century.
The .475 No 2 Nitro Express is a rimmed bottle necked cartridge designed for use in single-shot and double rifles. The .475 No 2 Nitro Express is a very large, impressive cartridge, the empty round is 3.5inches long with an overall length of 4.26inches.
The standard factory load fires a 0.483inches diameter 480gr bullet at 2200ft/s, although two powder charges were available with either 80gr or 85gr of cordite.
W.J. Jeffery & Co offered an alternate loading, known as the .475 No 2 Jeffery which fired a slightly larger 0.489inches diameter 500gr projectile at 2150ft/s, although again multiple powder charges were available, with either 75gr, 80gr or 85gr of cordite. Jefferys built a very fine handling double rifle for this round with a 24inches barrel that weighed only 11lb but retaining moderate recoil.
The .475 No 2 Nitro Express is one of several rounds developed in response to the British Army 1907 ban of .450 caliber ammunition into India and the Sudan which saw the development of the ballistically very similar .500/465 Nitro Express, .470 Nitro Express, .475 Nitro Express, and .476 Nitro Express.
Eley created the .475 No 2 Nitro Express by necking up their earlier .450 No 2 Nitro Express.
In 1914 and early 1915, German snipers were engaging British Army positions with impunity from behind steel plates that were impervious to .303 British ball ammunition. In an attempt to counter this threat, the British War Office purchased sixty-two large bore sporting rifles from British rifle makers which were issued to Regiments, including a single .475 No 2 Nitro Express rifle. These large bore rifles proved very effective against the steel plates used by the Germans, in his book Sniping in France 1914-18, MAJ H. Hesketh-Prichard, DSO, MC stated they "pierced them like butter."
The .475 No 2 Nitro Express is considered good general purpose round, suitable for all big game in Africa and India, its power is very similar to the .450 Nitro Express, with a larger diameter bullet; whether this is an advantage remains in dispute.
In his African Rifles and Cartridges, John "Pondoro" Taylor stated the .475 No 2 Nitro Express is "an eminently satisfactory shell and a certain killer - but don't let yourself be hypnotised by that great fat gleaming shell into the belief that you have something comparable with the atomic bomb to play with!"
Because of the larger diameter bullet, .475 No 2 Jeffery rounds cannot be fired through .475 No.2 Nitro Express rifles.
