C.A. Traverse .280AI scratching brass

[GW Hunter]

Got a brand new CA Traverse in 280AI that I haven't shot yet. Loaded up some new Nosler brass for barrel break in and when I checked to see how the finished rounds cycled I got some serious scratches from mid brass down to the rim. Looks like it is the feed rail. Can I just smooth them down a bit with fine Emory cloth or does this need to go back to the manufacture for repair?

Yes, immediately!

If it's on the rim that's the only place it could come from.

If scope the chamber, my CA MPR has a chamber that's out of round, there's proper freebore on one side, then lands all the way to the neck on the other side.
