I am a licensed Pyrotechnician and I use lots of Black powder for lift in firework shells. Have shot for Zambelli for over 13 yrs. As far as the BP at the LFS, I don't have a clue.

Hey!!! Graham & I agree on something
Just kidding there I was just thinking the same as you.
My take on Mark Weiss products is this: "What is this stuff?!!?"
I tend to avoid adding anything to my reef that I do not know what it contains...and to my knowledge none of the Mark Weiss product have a list of ingrediants! My position on them is that they are nothing more than well advertised and promoted snake oils!
