I use 0000 Steel Wool and a Sinclair Case Driver on a cordless drill! All of my cases are sorted for either Sighters or Record and numbered according to which row in the ammo box they sit. This does not allow for bulk cleaning. I use a Sinclair Primer Pocket uniformer driven by the drill to remove carbon from the pockets. I don’t clean the inside of the necks. I use a tapered neck design on my reamers for consistent bullet realse.
