txhunter58 This was not from the manufacturer. I doubt they would say it quite that way.

Yeah, it might be.

that's exactly what they are. expensive white 777 pellets. Ray

None of the Triple Seven Products are ascorbic acid based propellants (surgar based)

And in its orginal state T7 is White - color is added...

Muley Hunter

T7 is sugar based. The charcoal in T7 is sugar based instead of wood that's used in BP. That's why you don't see it listed in the ingredients. Just like you don't see wood listed in BP ingredients.

Think you are wrong... on that point and there are many sources out there for you to check.

If you check the MSDS it list:

Charcoal
Potassium Nitrate
Potassium Perculate
Graphite


Charcoal for the smoke and Graphite for the color. And unless Hodgdon filed an incorrect MSDS - Charcoal is charcoal.

Potassium nitrate is a chemical compound with the formula KNO3. It occurs as a mineral niter and is a natural solid source of nitrogen. Its common names include saltpetre (saltpeter in American English), from Medieval Latin sal petrę: "stone salt" or possibly "Salt of Petra" and nitrate of potash.

Potassium perchlorate is the inorganic salt with the chemical formula KClO4. Like other perchlorates, this salt is a strong oxidizer and potentially reacts with many organic substances. This usually obtained as a colorless, crystalline solid is a common oxidizer used in fireworks, ammunition percussion caps, explosive primers, and is used variously in propellants, flash compositions, stars, and sparklers.

Charcoal is the dark grey residue consisting of impure carbon obtained by removing water and other volatile constituents from animal and vegetation substances.



Sugar based powders use Ascorbic Acid. There is no ascorbic acid in any of the T7 products.

Ascorbic acid is a reductone sugar acid with antioxidant properties. Its appearance is white to light-yellow crystals or powder, and it is water-soluble.

Why do you think the charcoal is only for smoke? Is it just for smoke in BP?

I explained they don't have to list the sugar, because it's turned into charcoal/carbon. They only list charcoal.

You also better check why they use graphite too.

Muley Hunter

Read what it says about the T7 charcoal/carbon.
