Thread: Grey Birch 10/22 barrel

Hard to say from the photo, circumferential chatter marks in a buttoned barrel are cosmetically unpleasant and tend to pick up copper (in a centrefire), but don't necessarily affect accuracy (one of my most accurate rifles ever was a Savage 308 bull barrel that had highly visible but uniform chatter marks).
The Grey Mountain had both longitudinal striations and chatter marks, with the lands very 'shallow' and the edge of the lands poorly defined in places.
I shot it first before scoping it because its a truism that 'borescopes can steal one's joy unnecessarily', paramount is how it shoots and secondarily how easily it cleans, borescope appearance is a very distant third in importance. I consciously try not to be a 'borescope geek', but sometimes it can add information re cleaning or occasionally explain some issue that isn't apparent to the naked eye. @Ultimitsu hope we're answering some of the questions..
