While trying too remove the scope mounting bases from a recent action purchase. The previous owner had lock tited the base screws which resulted in twisting the torx driver off in the screw head. Luckly it was the scope base screw hole opposite the front action mounting screw. While setting the action up in the mill to drill through the screw I notice the action rocked when placed scope base down on the mill table. It was like the front base was at 12 oclock position and the rear base was at the 12:10 position. I'm sure when the build is finished it will be interesting getting it sighted.
