Just bought a new Mossberg ATR 270 and a leupold bore sighter. Lined the scope with the bore sight the best I could with but it won't line up perfectly with the both dials. It's maybe two turns out to the right and low. Both dials are turned as far as they can be to the right. I took a couple shots at 50 yards and it shot 4 inches low and 6 inches right. The scope is tightened down but I decided to remount it thinking it was off. Now it's all F up. bore sight is level but is way to the left of the scope (edge) now Any clues guys?
