Chosen answer: According to Wikipedia: "Cordite is a family of smokeless propellants made by combining two high explosives: nitrocellulose and nitroglycerin, i.e. it is a double-base propellant. However, Cordite N, a triple-base propellant is also used. Cordite is classified as an explosive, but it is normally used as a propellant for guns and rockets." So yes, it works.
