Ballistite = double base powder with

In the simpler version of this method, a double based powder of small size is made by conventional solvent methods and thoroughly dried. The required amount of this powder is then placed in a beaker of cellulose acetate or ethyl cellulose and the voids are all filled with desensitised nitroglycerine. The curing process consists of heating to temperatures of the order of 80°C for a prolonged period and on cooling, the mass becomes a gelatinous body similar to cordite or ballistite. 

Cordite is a double-base powder (NG NC typically 55 37% by weight) with mineral Jelly gelatinized by the action of acetone. The term comes from cords of wood, the source of cellulose used to manufacture nitrocellulose. Ballistite is the United States term for much the same material (NG NC around 40 60% by weight).
