I've never seen the point in breaking in barrels either. I've had some accuracy issues with new muzzys, but they were fixed by either free-floating the barrel and/or glass-bedding the action. From what I've seen, the barrel was not the culprit. I own CVA's and a Knight, and none of them required a barrel "breaking in" to shoot well. For example, my Knight shot a 1/2" 3 shot group at 50 yards (I know, not 100) with shots 4,5,and 6 out of a NIB rifle.
