(a) forming an aqueous paste of a major quantity of potassium nitrate and minor quantity of finely divided short fine cellulose fibers,

(b) forming a cup-shaped cartridge having an open end and a closed end of said paste under sufficient pressure to produce, after drying, a sufficiently dense, consumable cartridge that is also water-resistant, and

(c) drying the formed cartridge, and

(d) filling the dry formed cartridge with black powder, and

(e) closing the open end of the cartridge with a projectile.

2. A method according to claim 1 wherein said paste is formed 70-93 weight percent of said nitrate and 30-7 weight percent of cellulose fibers together with sufficient water to form a paste.
