You gotta be real, real careful doing that. You can easily over-relieve it and dangerously reduce case support. Sounds like you did it right, since I see the words “polishing wheel”, hopefully accompanied by rouge.

The best thing to use is a cratex point with a dremel tool tho they seem to be getting harder to find. I am down to my last one and it is almost worn out.

It removes virtually no metal but polishes better than anything I have ever seen.

I have been amazed at the poor finish of feed ramps on expensive guns which were otherwise beautifully finished. I specifically recall a Browning Hi-Power which had several deep tool marks in the feed ramp yet was otherwise a work of art. It actually fed perfectly anyway so I didn’t try to remove the gouges just polished them.

Before I did this, I called a buddy of mine who's qualified. He told me that it would take a long time, but to use a polishing mop and rouge. It took a long time, but in the end it was very slick and shiny and fed EVERYTHING....SWCs included! I did this same thing to a Walther PP/S that a friend of mine owns...shoots the .32ACP. It worked as well too! :-)
