Yes, correct on that point. As best I know the graphite coating on smokeless powder is involved in it's retardent value and used to control burn rate to a degree but that's about all I know on the point. I'll have to ask a friend who is actually involved in the testing of ADI Powders for a more explicit explanation if he is allowed to share any more knowledge.
Probably a point for another topic which I'm sure would interest many. I do know that the paper pulp, forget the exact type, that is used to make our powders is imported from Europe.
The making of smokeless single based (Nitrocellulose) powder.
So, in the photo above, the old matchbox base has a purpose but slightly different to the brush. See, a hint.
