I'm with Gwpercle on motor mica. I've been coating LLA bullets with it for years. After the lube is on, I let the coating dry to the tacky stage, put them in a tub and tumble them while sprinkling the mica dust on them with a perforated lid salt shaker.
I've also shot a lot of the TL .38 Wadcutters as-cast with no sizing at all and found them exceptionally accurate when used that way.
