I have 2 custom guns 270WBY & 300WBY both with Nightforce 20 MOA rails and Nightforce scopes on them, one an NXS and the other ATACR. I was thinking about just using the ATACR scope and switching back and forth between the two guns, wondering if anyone else does this and how accurate it is when they switch back and forth between the two guns? I'm using American rifle Co. Rings.
