Thought I would try my hand at this. Bought Eastwood Dark Green powder. Used a number 5 container, shook and swirled it till my arm hurts. Couldn't get it to adhere to the boolits.
Warmed them up and tried it again it did a little but not much. ran them through the oven, and then while still warm tried it again. Got a little better but not what I was looking for.
