The Smokeless Powder Company (S.P.C.) manufactured various high explosive powders for use in torpedoes, artillery shells, small arms ammunition (for the military and sporting) and mine blasting. Their rifle line of powders was called "Rifleite". Rifleite was a completely gelatinised smokeless powder, made in the form of flakes. A variety was also introduced for use in shotguns and was called "Shot-Gun Rifleite". The company was a world leader in its high explosive powders and had over 100 employees. It was the first British company to export smokeless powders to the US.
