A gentleman on another site knows more about blackpowder and the substitutes than anyone else alive. He has extensively tested the APP powders. His tests show APP powders to be no more hygroscopic than blackpowder or the other BP substitutes.
It actually produces moisture when fired according to APP's own website And it is very hydroscopic . So first they suck moisture . Then they produce moisture. So regardless of the only living expert and his tests , my results have proven to me that its the worst powder produced , You can have it all . I will stick with blackhorn and 777
