I have looked at several trade lists from the 1700's and all they ever mention is powder and lead. There is no distinction between various grades of powder. The lists I am talking about are from trade posts on the frontier. Gary Brumfield has talked about there being various grades of powder, but I believe he is talking about more settled areas??

Randy,
By way of "grades", do you mean specific grain sizes in the old writings?
The grain sizes we now use, 1F down through 4F, did not come into being until roughly 835 to 1840 when the gunpowder industry "attempted" to standardize grain sizing. It was at that time, 1836, that du Pont came up with the term "Superfine" which became a trademark of du Pont.
In the 1700's well into the 1800's you see the terms "rifle powder" and "musket powder" used frequently.
With the Lewis & Clark expedition they ordered "rifle powder" and "best rifle powder". You sometimes see this same terminology used for sporting type powders.
In dealing with the large military muskets you see the same powder used in the pan as in the main charge.
The musket powder of the 1800's might best be described as an equal mix of our 1F and 2F grain sizes. From a number of screen analysis that I did on 1800's rifle type powder most proved to be an almost equal mix of 2F and 3F grain sizes. What really surprised me was a sample of a rifle type powder brought into the U.S., from England, around 1880, Hall & Sons, that was also this equal mix of 2F and 3F.
According to my buddy who worked at the Hagley Museum, "the grain sizes we now use were first introduced in 1836 but were not used as such until late in the 1800's." That was his response to the data I gathered looking at grain sizes of old powders in the lab.
With the military muskets where the lock was primed with the 1F/2F grain mix you see large frizzens throwing rather large sparks to ignite the powder in the pan.
With the rifles you have finer powder and smaller frizzens.
That raises the point that lock scale and powder grain size were connected?
