W.J. Jeffery's bolt-action dangerous-game rifle in the proprietary .404 Jeffery cartridge. The .404 Jeffery (10.75x73) fires a 400-grain bullet at 2,125 fps for ~4,020 ft-lbs — a rimless design for reliable feeding in magazine rifles. The cartridge outlived the company by decades, being adopted worldwide. Jeffery went dormant in the mid-20th century.
