John Rigby & Co chambers the Big Game Rifle in 404 Jeffery for clients who want a powerful but recoil-moderate dangerous-game cartridge in a standard-length Mauser action. The 404 Jeffery fires a 400-grain bullet at 2150 fps from a cartridge that feeds reliably from a modified standard Mauser action, unlike the 416 Rigby which requires a dedicated magnum action. Rigby's 404 Jeffery Big Game Rifle has been gaining popularity as a practical alternative to the more famous calibers.
