Just so you know, the 'carbon burning compound' he mentions below is Vitamin C

TRIPLE SEVEN, BLACK MAG3, GOEX CLEAR SHOT
Now we get into an area where the muzzleloading industry has drifted into a mess of double-talk, sidestepping, and confusion. These propellants have nothing in common with true blackpowder at all chemically; no sulfur is present. Nor is charcoal present. They are still carbon-burning propellants, though, of the deflagrating (fast-burning) type. They are measured volumetrically, but only Goex Clear Shot can be considered a black powder performance substitute. Triple Seven and Black Mag3 are far hotter (or more energetic) than good old blackpowder, and produce higher velocities and pressures than blackpowder can. Still burning carbon, the carbon-based fuel burned here is from the sugar family-not from wood (charcoal). These propellants are actually far more modern than nitrocellulose based powders. In the case of Triple Seven and Black Mag3, they have only become available within the last couple of years.
Referring to Triple Seven and Black Mag3, the only thing that they have in common with blackpowder is they can be volumetrically measured with old blackpowder powder measures. They are not as corrosive as blackpowder (Black Mag3 claims to be non-corrosive), have little in common chemically, and produce more pressure, heat, and velocity than black powder. They are considered smokeless powder by the DOT, and should be used with caution in older muzzleloaders-- as there is no way that 100 grains volumetric charge of Triple Seven or Black Mag3 can be considered "the same" as traditional blackpowder. They are still relatively inefficient propellants, leaving behind close to 50% of their mass as non-combusted, solid residue. Referring to Triple Seven, that 50% unburned material is substantially less fouling than blackpowder for the simple reason that a 100 grain volumetric charge of Triple Seven, though it produces more energy than blackpowder, is far less by actual weight. More directly stated, you still have about 50% of the garbage left, but you start with less garbage to burn in the beginning.
