From what I can find it seems that T7 actually is a sugar based propellant. Which is what my original point was. But then some said it was not sugar based. Bu everything I can find says it is.
I also asked about BH-209. And whether it was, or was not sugar based like T7?? No one answered about BH-209. Does anyone know what the BH powder is derived from??
And I also do not understand the big deal about why a powder has to have charcoal if all it provides is smoke. If it serves no purpose then why put it in there?? And also if it serves no purpose then the powder should not be considered a BP substitue!! It should be considered Smokeless Powder?? If the charcoal is not needed for the actual momentum of the projectile??
Me thinks someone is trying to pull a fast one?? Tom.
Tom, I have not come to the same conclusion as you have on T7 the listed ingredients in T7 do not include sugar or even Ascorbic acid. THere is some speculation that the Charcoal listed might not be wood charcoal and that is certainly possible, after all you can make charcoil from news papers - just burn it.
The two different Potassium's that are used are certainly is not sugar. And do not believe that Graphite is either.
When you look at the ingredients for White Hot - T7 without Charcoal or Graphite you can see neither is needed for the powder to work. They are cosmetic.
BH...
Here is some additional information...

Also whoever stated that hogdon considers 209 smokless, are you just being funny or was that statement made by a spokeperson for hodgon, just curious
Yes, a tech advisor at Hodgdon told me that. I called to see if they were working on a product to compete with the BH209. (I am a FFL dealer)
The first thing out of his mouth was "you know thats smokeless, right ?"
He also said Hodgdon had several oportunities to market it but chose not to. He said they were not satisfied with test results they had with it. I opened a container of BH209 I recently obtained to test in my NEF and Savage. I must admit the sniff test is like smokeless. You reloaders know what I mean..the solvent smell..
After that call I had western powders fax me a MSDS on BH209.
The main component is Nitrate ester. I did some research on explosives then. My take on this is that nitrate ester is a "general" or "group" term of certain explosives. This type of explosive includes Dynamite, Nitroglycerine, RDX, C4, PETN, Semtex H, Nitrocellulose and smokeless powder.
I think marketing BH209 was a good idea. I have not tested it yet in my guns but from what results some others on this forum have had, I am expecting good results.
The only thing that is a turnoff is the high price. It was intended to fill a niche, in my opinion, of those wanting the performance and non-corrosive..clean burning qualities of smokeless. Being volumn comparable with BP is also a plus for those used to BP powder measures rather than weighed charges.
There was an extensive article written in the January/Febuary 2009 Vol 62 No. 2 of Single Shot Rifle Journal Magazine. Starts on page 13. I chemical analysis was down on the powder. That is the first known article that I have seen that discovered small amount of sulphur in the powder.
The information clip is from that article. I could email the whole article to you is you would like it complete...
