Tumbling the powder might do some of what you suggest? I bet it would result in more fines and rescreen dust and I get enough of that already - so for me - not worth the extra time and hassle - If my powder was not working well and I was getting inconsistent results then maybe -- but thats not the case - I am very happy with results and would rather spend the time shooting .
