I bought a rifle advertised as "new in box" on gunbroker. Picked it up from the FFL and a quick inspection looked good. Then I got home and cleaned it. Dozens of patches with Butch's Bore Shine kept showing blue indicating copper. Then I looked at the bolt face. There is a powder ring and a red waxy residue (see the photos). Is it really possible that this is a new rifle? Any idea what the red residue is? How many rounds does it take to produce a powder ring like this?
