The color issues is

That not all colors of powder stick to lead bullets the same. If you are a garage guy tossing bullets in a plastic pail with plastic BBs to get the static electrical cling to bond the powder to the bullets something like bright red from Harbor Freight sticks much easier than say flat gray does. Now if you spend a few dollars and buy a powder spray gun any color will work but they are certainly much more involved to coat that way. There is a strong electrical charge coming from the end of the nozzle that will zip that crap out of you if you are not really careful, plus you have to wear heavy rubber gloves and a resporator mask when using a spray gun. Big pain.
