Black Mag Powder

[Rock Fish]

Today I was reading an article in the Feb issue of "Shotgun Sports Magazine" on using tungsten shot in muzzle loaders. The propellant he was usingis "Black Mag 3 Powder. I don't recall seeing that powder listed in the topics I've read here. Does anyone use it? If so whats the pros and cons? From what I read in this article its seems to have the performance of T7.

Pretty decent powder.

Biggest pro; little residue and don't have to swab between shots.

Biggest con: Lost its distribution network, so only available directly from manufacturer, so have to pay the hazmet fee.
