777 differs from pyrodex, which i was aware of. the debate was if it was sugar based. i have read up on all the various BP subs and have never seen anything to make me believe that 777 is sugar based.there doesn't seem to be any sulpher or charcoal either.salt based products yes lol.. trade secret maybe!!!
