well, because I've been told "Cowboy Load" doesn't mean it has to be black powder, back when I sold the stuff at a gunshop in Tucson. And yes, from what I've been told, a "case full of black", what I loaded just two nights ago, doesn't have enough energy to hurt modern steel. That was homemade 2F, about 78%, loaded to crunch of 1/8 inch, meaning the bullet compressed the load about 1/8th of an inch, same 200gr Lee cast seen above with SPG Tropic lube in the groove. These should be mild little poppers - last time I fired this powder in this revolver, it generated just over 550 FPS, but the load was lighter. Maybe I'll break 600 FPS this time.
