Safest way to make black powder?
WEBNov 9, 2018 · The only "safe" way is to "hypermill" each ingredient (dextrin with the charcoal) separately and then combine them to premeasured water to make a putty ball and screen it to make the grains. Dry and sort by mesh size. Don't take chances, don't break the law. Right, process can be followed. Thanks for this advice.
