Where RS (Rifle/Shotgun) is equivalent to FFg black powder and P (Pistol) is equivalent to FFFg black powder on the Fg (coarsest) to FFFFg (finest) granularity scale. While Pyrodex offers improved safety and increased efficiency (in terms of shots per pound of powder) over black powder, the level of fouling is similar to black powder as Pyrodex ...
Military rifle propellant was manufactured in batches in a procedure taking about two weeks [7] from treating cotton linters with nitric acid, through curing the extruded grains to evaporate excess ether and alcohol, and finally coating the dried grains with DNT and graphite. Each batch had somewhat different reaction rates, so testing was ...
