Reconditioning brass rims

Is there something available that can smooth out (at least a little) extractor
marks/dents/etc on the rims of auto brass?

A casepro roll sizer was designed to resize the rim and clean up the extractor grove. I automated one shown in the photo and video below.

You can “press through” size some cases but that doesn’t clean up the extractor grove and can leave burs of it’s own.

And a video

I keep a needle file on the bench and just touch up the rims as needed when running them through my case gage.

I throw them out. I can't see doing this unless I was shooting a rare cartrige.
