I use both the Ultrasonic and a tumbler, the tumbler is easier. I drop it in run it, pull it out, give it a good shake and I'm done. The Ultrasonic I let the cleaner heat up run it a few times and then rinse it and while it's still wet I blow out the primer pockets with compressed air and let dry over night. . I tumble all my practice ammo and use the Ultrasonic for match ammo they are both well cleaned but with the Ultrasonic my primer pockets are spotless. I also run tumbled brass through a universal deprimer in my Reloader just to make sure nothing is stuck in the primmer pocket.

Shoot as many matches as you can, it's unreal how helpful your fellow shooters will be.
