Mad Monk, you're a wealth of information. Interesting.
I thunked on the Black MZ after shootin it and mentioned to my lovely wife it seemed a lot like smokeless powder. She just said ,"oh well". I wasn't too far off the mark with my thunkin. I wish Alliant would bring it back and...sell it a little cheaper. I could tell that powder seemed to make faster velocity.
Triple 7 FFF is a fast powder and....27gr FFF of it harmed my pistol. The triple 7 FF is better for a pistol and I kinda like it. The real black powder is on the top of my list though. Ifin it was good enough for Jeremiah Johnson it's good enough fer me. The book," Crow Killer", from Dixie Gun Works about Jeremiah is a good read.
