Dies scratching the **** out of brass!

My RCBS 357 resizing die is scratching my brass. I have resized 200 357 NICKLE cases with the die, and that's when the problem started. The inside of the die looks smooth as silk, but evidently it ain't! How can I polish the scratches out? I thought about using 0000 steel wool wrapped around something in my drill to try to polish it out. Or just buy carbide sizing dies and start over. Any advice appreciated.

Same thing happened to me with a set of 44mag dies. The sizer die leaves very noticible scratch mards up and down he case. I tried some polishing compounds but without success ... a new carbide sizer die cured the problem .. This was an old, old set of Lyman dies ..
