 Unlike "Cordite", "Rifleite" was a flake powder, and contained no nitroglycerine.Excessive wear of the shallow Lee–Metford rifling with all smokeless powders then available caused ordnance authorities to institute a new type of barrel rifling designed by the RSAF, Enfield, to increase barrel life; the rifle was referred to thereafter as the Lee–Enfield.After extensive testing, the Committee on Explosives selected "Cordite" for use in the Mark II .303 British service cartridge.
