.500 Jeffery

The .500 Jeffery is a big-game rifle cartridge that first appeared around 1920, and was originally introduced by the August Schuler Company, a German firm, under the European designation "12,7x70 mm Schuler" or ".500 Schuler". When offered by the famed British outfitter Jeffery's Guns, Rifles, it was renamed the .500 Jeffery so as to be more palatable to British hunters and sportsmen following World War One.
