I finally got to try some Sherwin Williams powder.... I got a gray, and Kubota orange.
I did some bullets with the orange, then decided to try the gray. As I shook out the bullets into my mesh tray, there apparently was still some orange powder on it, which the gray ones picked up. These are the ones in the plastic tub.
I then did another batch with mostly gray, and added a little orange to it. I turned them a sort of brownish/bronze color. This pic is four of them with the plain gray beside them..... Different.
This powder appears to work very nicely.
As an aside.... I have found that parchment paper works much better for "no stick" than the no stick aluminum foil... I used a piece of it for two bakings so far... it turns sort of brown, but the bullets don't stick to the paper at all.... just pick 'em up.
