The little LEE primer pocket tool that chucks in a drill/driver is what I use. Whether or not you should clean primer pockets is up to you and the amount of time you have. It is not a necessity for plinking ammo, but for my defense loads I use nickel once fired cases and the primer pockets get cleaned pretty quickly. I have a Ryobi drill/driver that has vertical and horizontal spirit levels to make sure I'm square to the case and I lock its trigger for highest RPM and allow the driver/pocket cleaner to sit on the pocket just long enough to get the full weight of the drill/driver then proceed on to the next case. Typically, I can do 200 cases in about 5 minutes.
