No not black powder, I don't even own a black powder firearm.
If you're thinking my screen name has anything to do with black powder it does not. My screen name has to do with my current profession, since I make a living dragging coal around. About 14-17,000 net tons of the stuff at a time, divided into 120 to 135 connected containers. I also drag some freight around, but where I work mostly coal.
