Load a round and eject it from your gun and make sure that it's not scratching it in the action. My Remmy VTR was doing that on every case.
I sent it off to Remington and they returned it 3days later saying it was normal.
Finding thisunacceptable so I found the bur in the action and worked on it slowing with a jewelry file and emery cloth and it now it doesn't scratch the cases anymore.
