I didn’t mean to Pooh-foo your idea. I, too, am quite interested in making my own smokeless.
For the science and self sufficiency of it.
This is where I got my nitric acid.

It is of high enough mole to work. Not all acids of the same name are the same.
I had thought of using MCC, Micro Crystaline Cellulose filler, dietician product, as the cellulose, as none of my saw dust or planer shavings are clean enough. The raw cotton filler for blankets may also work.
Making nitro cellulose is as you describe, just the same as nitrating glycerine, with all the same hazards. Runaway nitration is one of these.
Graphite can be found at a feed and supply store as seeder lubricant. I now have a lifetime supply with my one pound. (Works well for spreading lime in the lawn. Still have most of it...
I imagine it’s making a mess in my shop as we speak.)
Like good red gum black, the process must be identical with each making to even begin to get a useable product. Unlike the Holy Black, there are many more variables to control during the production.
Since my organic chemistry began and ends with anion and cation exchange rates in organic soil Peds, and I found some kids along the way somewhere, supplies sit unused. After all the study my lack of confidence got to me.
(And sticker shock at the glass beaker store! Don’t they make that out of sand, not diamonds?! Turns out the acid is cheap.)
Because most of the manufacturing processes are closely guarded trade secrets, any video you make is one of few. Nitrating cellulose is pretty straight forward, actually turning it into gunpowder is the trick.
Be careful!
