In my experience I have found that the corn cob media is better for a finished polish on used brass, in addition to using cob media I add about 2 tablespoon fulls of Flitz Metal polish in the media. Have not has any issues of tumbling causing any deformity of resized/trimmed brass.
I was happy to get a brass tumbler and some walnut media for Christmas. This will be my first attempt at tumbling brass. I usually always reload new Winchester brass for rifles and never really had a need to clean any. With the current shortage of supplies, time to clean brass. I am thinking this will be fine, but thought I'd ask...I'm going to re-size to get the old primer out, and trim case to proper length. Next step will be to tumble. Any potential issue with deformation of cases during tumbling? I really doubt it, but what's your process of steps when reloading? I'm going to toss in some Hornaday, Remington, Winchester, and Federal brass to see if any clean up nicer than the other.
