Mine is a vibratory brass cleaner. I use the lyman brass cleaning solution. I leave them in for about 2 hours, and check to see how clean they've gotten. I'm not looking for shin brass, just clean brass. About two to three cap fulls puts enough into the media to assist in cleaning.
I anneal with AMP after each firing, don't turn necks, and use STM tumbling for 4 hours.
Case length is still within spec, about 2.575 to 2.580 so i haven't trimmed yet.
I have been hand loading for about 4 years, self taught from watching videos, reading here, and reading articles.
