I have experimented with everything except Hi-Tec coating , choosing to use a magma lubesizer for most of my cast boolits . But I will still tumble lube a big pile of 38 wad cutters with a lee / Johnson tumble lube mix , or pan lube a few for my inline . PC is pretty simple with the shake & bake method and could probably cover all of my shooting .
It's nice to have choices .
