Savage Model 40 bolt scuffing?

[ELMOUSMC]

I hope I don't have a problem and that I am just being over sensitive about my new rifle.I was at my range running some tests on some reloads that I had worked up.I got back up to the house and started to clean my rifle when I removed the bolt I noticed 2 parallel lines(not scratches or groves) more like scuffing that would be on the bottom of the bolt when closed.I don't feel any drag and there is no wobble in the bolt,anyone have any ideas ELMO
