Used too. Used to tumble and clean primer pockets... Now, I tumble rarely, and and rarely clean the primer pockets of my revolver cartridges. When I feel they need it, I'll do it, but never every time. Never had a problem with primer seating nor a difference in quality of end product.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
