Another development to circumvent the British prohibition of the .450″ in India and the Sudan. The 475 No.2 was the “standard” load with the 85gr. cordite load and 480gr. bullet as opposed to the 475 No.2 Jeffery which was loaded with the 500gr. bullet. These 2 cartridges were interchangeable, provided the regulated barrels on the doubles shot at the same point of impact for the different loads.
