Sannadex Powder

In the case of T7 carbon is not need for the reaction but with the addition of charcoal you have a product that when burned creates smoke or at least some smoke. That is the sole purpose of the charcoal in T7. So it's quality is not as important as it is in real BP.
So again you may be right, but really i acually suspect the same charcoal used in Pyrodex is used in T7 but only a lot less of it, as it is not necesary for combustion. I can not imagine that Hodgdon would not use the same products that they already have under contract, just with T7 they do not need as much of it. Well actually as White Hots show - they do not need any except they were trying to meet our expectations of what a BP sub should like - so add charcoal for smoke and graphite for black powder.

can you find anything in regards to 777 that states it contains any type of sugar base. Ray
i'm an EOD guy for nearly 50 years. Know several explosive forensics types; if 777 powder contained sugar i believe they would have told me. The presence of sugar byproducts should make post detonation analysis easier.
Triple Seven and Black Mag3 are far hotter (or more energetic) than good old black powder, and produce higher velocities and pressures. Still burning carbon, the carbon-based fuel burned here is from the sugar family, not from wood (charcoal).
The analysis of 777 powder and residue from a simulated disrupted pipe bomb shows no evidence of sugar/sugar residue that i can find.

Sulphur is added to BP to lower the ignition temperature.
Believe it or not there's a powder that uses only two of the ingredients of black powder which omits the sulphur and it works almost the exact same.
It's only ingredients are ~85% saltpeter and ~15% charcoal by volume.
