Polishing rifle chamber

Using a borescope, I have detected some scratches on the chamber walls and neck area of a new rifle ( never fired). These scratches are just barely visible with the naked eye, but with the magnified bores cope they are obvious. Chambering a case and extracting it the scratches don't transfer to the case -- but they might under normal firing pressures.

I'm wondering if I can lightly polish these out using 600 or higher grit sandpaper without messing up the chamber dimensions. This is a 260 rem if it matters.

If so, how would you go about it?
