Black Mag BP substitute

Does anyone have experience with this product? The company's claims seem "too good to be true" but I would like to hear what people who have experience with it have to say. If even part of the claims are true I would be interested in trying it out...

    BlackMag3 came out about 4 years ago.
    At that time the manufacturer billed it as "non-corrosive."
    I noticed that Cabelas did not bill it as "non-corrosive."
    Nevertheless, I bought a pound to try in my cap and ball pistols.
    I am tired of cleaning them.

    I ordered a pound from Cabelas. With hazmat fee it cost over $50!
    I loaded one cylinder in my .44 and fired.
    The idea was to let it set up without cleaning.
    Thank God, I did run a few patches down the barrel, otherwise, no cleaning.
    I had meant to let the pistol set in the drawer for 2 weeks. I screwed up, and let it set 8 weeks.
    When I got the pistol from the drawer, the hammer and cylinder were covered with red rust! I was not happy.
    Thank God, the barrel was ok.
    I spent 3 hours cleaning up that poor pistol.

    A few months later, Cabelas quit carrying BlackMag3.
    I don't know why, it is pretty good powder otherwise.
