I'm with Cayugad on this one. I can't see how taking the barrel off with the scope mounted on the barrel could have much impact on POI, althoughI would try to make sure I put the same amount of tension on those two barrel mounting screws every time I took it off and put it on.
I agree. Tighten the screws the same every time and you should be fine. I've never had one move.
