btw BH 209 is not legal in CAS shooting. They aren't fooled that it's a smokeless powder. Any BP or sub that won't clean up with water is smokeless.
btw btw.. Does BH have charcoal for smoke?

In T7 and since it is also smokelss, you do not need it either as shown in White Hots! Today I think you could roduce and sell it as a smokeless BP sub, but when it was forst brought out I am not so sure. Still don't think I would like it if it were white though. I prefer 'black' gun powder.
Do you get the idea it was added to appease the old fogies that believe that BP or a BP must produce smoke to be a BP sub.

I've seen no proof from anybody that charcoal is added to subs for just smoke.

we also know charcoal isn't needed in 777 to make it ignite. so take a wild guess as to why they add it.

Black Powder Ingredient Charcoal:
Charcoal is the fuel used in the making of black powder, it's portion of the mix is 15% by weight. To make a good black powder you have to use a good charcoal. There are differences in wood types and charring temperatures to produce good charcoal.
Wood Selection:
Below you will see a list of wood types, these are listed numerically as to the quality of black powder they will produce when charred properly.
(1) Willow
(2) Birch
(3) Fir
(4) Oak
(5) Beech
(6) Ash
Note: All the above wood types listed, when charred properly and then used as a fuel for black powder will produce an excellent quality black powder.
Charring Time:
The charring time has little influence on the carbon concentration of charcoal.
Charring Temperature:
The charring temperature is very important to the carbon concentration of charcoal. For black powder purposes wood should not be charred at more than 800°F. Charred at higher temperatures it looses flammability. Charcoals like those used for barbecuing are not suitable for making black powder.
Most of the charcoals that are used for the making of black powder are charred at 750 °F. Brown charcoal, looks brownish in color is charred between 500°F and 700°F, it's very flammable and excellent for making black powder.
So if the sub's do not require charcol. And charcol is only added to make smoke appear. But that smoke is totally unnecessary for the actual combustion of the powder. Then the charcoal is only added for effect. So therefore the powder that adds charcoal for "effect" only should be listed as "smokeless Powder". Since the smoke is NOT necessary for combustion.
So basically these advanced powders are a less powerful smokelss powder.
Smokeless really does not have any thing to do with the classification, more it is what the powder is made of. The modern smokeless powders that we normally think of are Nitrocellous based powders. BH is the only sub that falls in that realm, none of the other BP subs are using Nitrocellouse for ignition.
It kinda started here...
Henri Braconnot discovered in 1832 that nitric acid, when combined with starch or wood fibers, would produce a lightweight combustible explosive material, which he named xyloïdine. A few years later in 1838 another French chemist Théophile-Jules Pelouze (teacher of Ascanio Sobrero and Alfred Nobel) treated paper and cardboard in the same way. He obtained a similar material he called nitramidine. Both of these substances were highly unstable, and were not practical explosives.
Guncotton remained of limited use. For firearms, a more stable and slower burning mixture was needed. Guncotton-like preparations were eventually prepared for this role, known at the time as smokeless powder. The first practical smokeless powder made from nitrocellulose, for firearms and artillery ammunition, was invented by French chemist Paul Vieille in 1884.

And therefore SHOULD NOT be considered as a sub. For Black Powder(Since smoke is a required effect of blackpowder). These powders should be considered as low power subs. for smokeless powder. But definitely not as a sub for BL since the charcoal is not a "necessary" ingredient for combustion.
Black powder substitute
From Wikipedia, the free encyclopedia
A black powder substitute is a replacement for black powder used in muzzleloading and cartridge firearms. Black powder substitutes offer a number of advantages over black powder, primarily including reduced sensitivity, reduced fouling, and increased efficiency. Due to property insurance and federal transportation regulations, black powder substitutes also can be transported and stored in interstate commerce in the United States using smokeless powder regulations, instead of the much more restrictive black powder regulations. Because of this, black powder substitutes are thus becoming more commonly available than traditional black powder, which has largely vanished from the shelves of most retailers.
[quote]I think these powder mfgs. are just trying to skirt around laws of states that do not allow smokeless powder in MZ's. But why else should the powder smoke. If not for "effect" only.[quote]
But somewhere these laws that you speak of - really rules not laws created by DNR or Fish and Game Departments are were meant to implie eveyone's normal conception that a smokeless powder was a 'Nitrocellouse Powder'. Some states have even changed their rules to now say 'Nitrocellouse' powder and are now basing there rules on the definition of a BP substitute because it is safer and for marketing reasons. Actually most states have changed the rulings to go be the sub definition that is exactly why BH is legal in most states - much to the disappointment of a lot of people.
I realize this is just for discussion. But from what you other guys are saying. You could just as easily use a powder like Trail Boss as a sub also. Except it does not smoke?? Just an opinion. Tom.
And you are right - discussion topic ony - nothing about right or wrong or anybodies personal feelings...

I honestly do not know, but it could be most anything even paper pulp will produce charcoal and when it is reburned under a much higher temperature of powder ignition it will produce smoke.
Remember charcoal is only listed in T7 - none of the surgar based products use it in their formulas.
But, to your question - again I would suggest you look at IMR White Hots - same powder as T7 without the two added ingredients and produces the same power as T7, actually IMR(hodgdon) says greater power but I have not seen anyone confirm that - that is the only proof that that I can offer...
And originally when T7 came out, Hodgdon said the same thing - they had to die the powder and add more smoke to make it appear to be more like real black powder.
How do you know the charcoal in subs doesn't add to the performance?
