I always disliked using the tumbler and the dust it creates, only cleaned if the brass was really dirty. I would clean the primer pockets and load em up.
But the ultrasonic is so easy. I deprime, toss em in the ultrasonic for 20 min then put them on a cooking sheet in the oven at 170* for 20 min, dries em right out.
Rifle brass, pistol brass, everything.
I put the brass and cleaning solution in a glass beaker, then into the ultrasonic tank of plain water. Works great, and no cleaning of the ultrasonic tank because it only ever has clean water in it.
