History

In response to initial case extraction problems with John Rigby & Company's revolutionary .450 Nitro Express, both Eley Brothers and Holland & Holland looked to develop alternatives that would match that excellent cartridge in performance. [2] Whilst Eley developed the completely new, mammoth .450 No 2 Nitro Express, Holland & Holland followed Rigby's example and loaded the old black powder .500/450 Magnum Black Powder Express with cordite, creating the .500/450 Nitro Express. The larger case capacity allowed the same ballistics at reduced chamber pressures to the .450 Nitro Express. [2] 500/450 Magnum Nitro Express was introduced by Holland & Holland for their single shot and double rifles during the late 1890s.

By the time the .500/450 Nitro Express appeared, the early issues with the .450 Nitro Express had been resolved, and it quickly became the most popular and widely used Elephant hunting round, leaving the .500/450 Nitro Express behind in popularity. [2] In 1907, the .500/450 Nitro Express's fortunes were further eroded by the British Army's ban of .450 caliber ammunition into India and the Sudan. In response to this ban, Holland & Holland developed their .500/465 Nitro Express. By the time the ban was lifted, Mauser's Gewehr 98 bolt actioned rifles offered cheaper alternatives to the expensive double rifles required by the Nitro Express cartridges.

Use

Ballistically the .500/450 Nitro Express is almost identical to the .450 Nitro Express and is considered a good large-bore round, suitable for all dangerous game.

One prominent user of the .500/450 Nitro Express was Theodore Roosevelt who carried a Holland & Holland double rifle in this calibre, along with a .405 Winchester and a .30-03 during the 1909-1910 Smithsonian–Roosevelt African Expedition. [3]

The term express was first applied to hunting rifles and ammunition beginning in the mid-19th century, to indicate a rifle or ammunition capable of higher than typical velocities. The early express cartridges used a heavy charge of black powder to propel a lightweight, often hollow point bullet, at high velocities to maximize point blank range. Later the express cartridges were loaded with nitrocellulose-based gunpowder, leading to the Nitro Express cartridges, the first of which was the .450 Nitro Express.
