Tumble Brass vs. Vibratory Cleaning

[fredhorace77]

I have always used a vibratory cleaner and recently purchased an Ultrasonic cleaner. I am looking into purchasing and cleaning with a Tumbler using Stainless Steel pins and liquid cleaner. If I tumble the brass after it has been resized do I risk jeopardizing the roundness of the case mouths?

Why do you run dirty brass through your sizer die?

I dont...I was trying to keep my question short and too the point...i guess ill have to give some more details...I first decap all brass...then clean it either with vibratory or ultra sonic cleaner...then i resize it and trim it..after handling all the brass I perfer to run it thru and clean it once more to get all my finger prints off of it. Keep in mind im doing 1500-3000 pieces at a time. I was researching the wet thumbler with ss pins and thought it might be best of both worlds...but i dont want to invest in it if it mess up my case mouths after it has been resized...if it does then ill just stick with the vibratory cleaner for the final polish

The wet tumbling would be a little aggressive at that point. If you leave brass in the tumbler too long it does beat up the end of the neck, raises a small burr on the O.D. side.
