Due to the continuing unrest in India and the Sudan in the early 20th century, the british Government was forced to ban military calibres of .303 and .450. The locals in these areas had a collection of ex-military rifles and in an attempt to prevent their use they were not allowed to be imported. The .450 was the mainstay of the Holland & Holland heavy battery and the company was forced to find an alternative.
It came up with a subtly different cartridge, the .500/.465 nitro express introduced in 1906. The cartridge was very similar to the now-outlawed .500/.450 nitro express. The case length was 3¼in and the bullet weight 480g. It was impossible to fire the new round in the old rifles.
The firm gave the .500/.465 the brand name “The India”. In .500/.465 achieved great success not only in India but in Africa and indeed all parts of the world. After World War I it had achieved dominance over the .450 and remains a very popular calibre to this day.
