From what I have seen, a light contoured barrel can walk shots after the barrel really heats up. This is why we shoot a 3 shot group not a 5. With a much larger countour barrel like a sendero, a guy can shoot a 5 shot group before you see any walking. From what I have seen. A rifle put together with less stress shoots inconsistently and a barrel installed to a action and then fitted to a stock with stress or not all put together with out stress will shoot very bad or inconsistent. This rifle shot really bad. Shot 3 shots and point of impact would be at 11:00 of point of aim. Let the barrel totally cool and shoot another 3 shot group with the exact same ammo. The group would hit at 3:00. So a six shot group at 100 yards would be an average of 6" and each 3 shot group averaged 2.25" With this perticulary rifle. I would expect there are a few issues not just one.
