I didn't bother to clean the bullets. I left the lube rings filled with compound. Just use dacron on top of your charge and seat bullet in case. Then you can clean case and shoot. It is messy as all get out but it works.Thanks for the information on a lapping charge Mike!
Did you see my other question - about the amount of lapping compound to leave on the bullet, and any negative effects it might have on the powder?
It would seem that the lube groove should be full of the compound - but it is awful soft/messy stuff - just touching it with anything, like a finger or the paper towel i use to clean the base of the bullet - pulls the goop right out of the lube groove.
