Is peening of the case mouths a thing or not when using ss pins to clean?
Also - primer pockets definitely come out 100% clean?
I currently ultrasonic clean, dry then tumble in Lyman red walnut media. De-prime after then clean primer pockets one at a time.

penning isn't a thing imho.
Primer pockets come out mostly clean, but not like new brass unless you let the tumbler run for a very long time.
I'm not sure why you do both ultrasonic and dry tumbling. Only one operation should be good enough.
I let mine run the full 3 hour cycle, my pockets are just like new![]()
Keeps my tumbling media clean. I have been using the same media for 3 years (just a top up once in a while).
Old walnut media is also not dusty.
I did read that leaving a pin in the case, then charging a case is a bad thing.

Don't pay attention to young morons, this old fart wet tumbles.
P.S. I prefer to be called chronologically gifted.

Interesting- is there any concern that the s/s medium breaks down the brass to a degree shortening the case life? I'm new to reloading and don't have a brass cleaner system yet.
