Cartridge Profile: .404 Jeffery

The .404 Jeffery is identified by C.I.P. as the 404 Rimless Nitro Express, with .404 Jeffery listed as an alternate name. It was developed in Great Britain during the early twentieth century for magazine-fed sporting rifles.

The cartridge earned a long-standing reputation as a practical African hunting round, combining substantial bullet diameter and dependable magazine-rifle operation without requiring the size and weight associated with the largest stopping cartridges.

It remains in use in historic rifles, modern production rifles, and custom dangerous-game builds.
