I use Lee Alox and a little white spirit, put it into a large Tupperware box with still warm (not hot) bullets and shake them until all are evenly covered. I make 300-400 bullets at a time, 1/2-3/4 inch of inox from the bottle, not the little spout and a couple of spoons white spirit. Shaking while dancing to Taylor Swift's "Shake it off" is about right.
Spread out and leave to dry overnight and you're away.
This may all be wrong, but it's what I do
