I use both. 16 min in the ultrasonic after neck sizing and shoulder bump then 10 min in stainless pins. Brass comes out cleaner and shinier than new. SS pins are awesome but if you run them longer than 30 minutes you get neck peening on the inside and outside edge of the neck. I only do this prior to length trimming my cases.

If you have some filthy brass that needs a trim anyway send them to me and ill polish them up for you.
