The 465 Nitro Express is a cartridge that Holland & Holland developed jointly with ammunition manufacturers in the early twentieth century as a direct competitor to the 470 NE. The Royal Double Rifle in 465 NE was popular in the Edwardian era among British officers and colonial administrators who hunted dangerous game across East Africa and India. The cartridge produces ballistics nearly identical to the 470 NE and the two are often considered interchangeable in practice, though they are dimensionally distinct.
