The .450-400 Nitro Express is a Nitro Express rifle cartridge that produced in two case lengths, 2⅜-inches, and 3¼-inches and intended for use in a single shot and double rifles. The latter is considered a classic Nitro Express cartridge.

The .450-400 Nitro Express loaded with a 400 gr. RN bullet with 42 or 43 grains of cordite and meant for use in newer rifles chambered for the .450/400 2⅜ inch case as this loading generates higher pressure than the Black Powder Express versions of the cartridge.
