Flash is made with about 30% aluminum powder. Just the folks at Morton Thickol about aluminum powder. It makes a great propellant but goes Boom when not handled right. fine grain black does not have the power per pound and is slower burn but "slower" is still very fast over modern smokless compounds. OTOH it is cheap and easy to get and stable for the most part. About 6 months ago I mixed a pound of 20 year old black powder with 10 pounds of wet dirt and chucked it out.
No worrez about ATF as no one would ever do anything like make a noise maker from paper wraped black powder.
