Stainless Tumbling Media and in love. Clean inside and out including the primer pockets. Always comes out looking like unfired brass.
Wow, even the pockets get cleaned?
That would save me a step in the load process if I could get them clean when tumbling. Walnut has never done any good in the primer pockets for me.
One thing I have noticed with the SS media is if you tumble 3 to 4 hours the media will ping the neck edge so you will have to clean up the lip before you seat a bullet. I ran into this problem when seating bullets in very tight seating die, the neck expanded enough that I couldn't seat the bullets in the case. Camfering the lip with a tool fixed that.
