they size the bullets without lube and then tumble coat them the way I hear it from four fingers. Right now the way I fluid coat my 20 gauge slugs it comes out about .621 without sizing and that it perfect. I did change the way I dip the slugs to putting the eyelet on the bottom. from reading here I agree that you do not need coating on the bottom or the bullet. I am going to try cleaning the bullet before dipping with alcohol next.
