The .475 No. 2 Nitro Express is a British rifle cartridge.

One of several rounds (including the .470, .475, and .476 Nitro Express)[1] designed and introduced between 1905 and 1910,[2] after the British Army banned the .450, in India and the Sudan,[3] all with comparable performance,[4] the .475 No. 2 was used in a number of double rifles. In addition, Jeffery chambered a slightly less powerful loading in his rifles.

A good general purpose round, it is suitable for all big game,[3] though somewhat overpowered for anything in North America.[3] Its power is almost identical to the .458 Winchester Magnum,[3] with a larger diameter bullet; whether this is an advantage remains in dispute.[5]

The standard factory load used 85 gr (5.51 g) of cordite over a 480 gr (31.1 g) slug, while Jeffery used a 480 gr (32.4 g) bullet which dropped 0.6 in (15 mm) more at 200 yd (180 m).[3]
