Dimensions thumb|center|450px 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.Hailey. 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. 500/450 Magnum Nitro Express was introduced by Holland & Holland for their single shot and double rifles during the late 1890s.Cheney Clive The .500 Nitro Express: African cartridges that made history https://africanxmag.com/2024/12/06/african-cartridges-that-made-history-the-500-nitro-express/ 24 February 2025 African Expedition Magazine Hunting 6 December 2024 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. 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.Massaro Philip Head to Head: .450 Nitro Express vs. .470 Nitro Express https://www.americanhunter.org/content/head-to-head-450-nitro-express-vs-470-nitro-express/ 24 February 2025 American Hunter National Rifle Association 14 June 2019 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.
