Well had part of a day at the range go south due to a loose scope at the rings. Leupold rings and bases on a 300WM. I certainly should have checked screws but never had this happen before. Scopes probably been on almost a yr. I use blue Loctite on the screws but 1 was pretty loose and 3 were not loose but questionable and the scope shifted forward plenty. Enough to put marks all the way around the tube about 1/2 inch. Sad... I shoot off a led sled and someone at the range mentioned this was a bit harder on a scope. Not sure I swallow that. Opinions? I imagine those in the know check scope mounts regularly ? Pretty sure I learned a good lesson here today.
