Martin - Firstly, I see nothing wrong at all with posting this. This kind of item is totally and without reservation part of “ammunition” and very interesting to boot. You are not discussing how much of what to put in what cartridge, so their is no “foul” here at all.
I see he is burning a charge in the palm of his hand. That is incredible. Can you tell us more about this? I saw recently something similar, but probably not identical.
In the current (February 2009 issue, page 34) of Guns Magazine. It is a product called “White Hots” and they are little cylindrical pre-measured, solid charges of propellant for muzzle-loaders put out by IMR company. No time right now to cover it any more than that.
