History
An early variant of the .450/400 family of Nitro Express cartridges, using a 3.25-inch case rather than the standard 3-inch version. Developed in the Edwardian era for African dangerous game in double rifles. The longer case provided slightly higher velocity; now superseded by the standard 3-inch version.
