I make it sometimes. I load cowboy pistol cartridges with it. You must get a formula by WEIGHT, and mix and screen properly. Then always flash test by putting a half spoonful on white typing paper and light. If the paper burns then the powder is too slow, usually because of excess sulfur or insufficient working. If the powder flashes and the paper is only blackened and doesn't burn, then it is fast enough to put into a black powder weapon.
