[QUOTE="specweldtom, post: 539105, member: 2580"] Jinx, I saw something like this in a 6mm BR barrel from an old-time very well known benchrest barrel maker. That barrel also had circular tool marks that were complete continuous circles across the lands and grooves like yours, only there were thousands of them, full length of the bore. The barrel was cut-rifled, and I believe the marks were made by the broaching tool chattering. I did not see the marks looking down the bore with a bore light, and could not feel them with cleaning patches. Only when I inspected the bore with a borescope after the first range session. It shot 1/2 moa during the break-in session, and didn't copper foul, but I decided I would rebarrel it with a Lilja. I figured a 6 BR should shoot better than that even with me pulling the trigger. Your barrel may turn out to be O.K., but you sure got crappy customer service. No quality barrel should look like that. Tom [/QUOTE]
