How many test shots does Winchester make at the factory?? I got a new XPR Hunter in .300 Win Mag., and I went to clean it yesterday. It was what I would consider filthy. I kept scrubbing and scrubbing and patch after patch after patch after patch kept coming out dirty. When I picked it up at Sportsmans, the box was sealed with single layers of tape, so I know no one in the supply chain took it out for a joy ride.
