1. In the art of making spherical, single-base low density powder grains from discrete particles of a lacquer of a single smokeless powder base and a solvent therefore, the method comprising the steps of(a) continuously forming a single-base lacquer into substantially spherical particles while entrained in a salt-free liquor suspending medium which is a non-solvent for the powder base and substantially immiscible with said solvent,(b) coating the formed spherical particles with a deterrent;
- and(c) rolling the particles to produce an oblate spheroidal grain of a specific gravity within the range of from about 1.15 to about 1.275.
