blackpowder and blackpowder replacement powder loading information is usually listed in volume charges. Simple enough, but uses grains ass the unite (mass). I assume a 100 grain mark on a volume measure is supposed to deliver roughly 100 grains (mass) of black powder if it were put on a scale. Not really much confusion until pyrodex and other black powder substitutes are used. While regular pyrodex can just be used with the same volume measure, the mass is actually less, but produces the same effect as the equal "volume" grains of black powder. Hodgdon's new powder, triple 7, suggest using 15% less volume for equivalent black powder charges.

What I'm curious about, is what actual volume measurement is supposed to correlate to a mass measurement of powder.
