S.O.S.-New Scope setup looks 'left'...a lot!
I'm getting ready to sight in my new scope and notice the scope crosshairs are looking way to the left of the bore. I'm talking on the order of 2 inches left at 30 yards or so. Even with full windage dialed in, I still can't quite get the vertical crosshairs to line up with the bore.
I took the scope off and played with all the screws, trying them back on a dozen times. Nothing. Then, I switched rings fore and aft, same result (tells me it's not the rings or it would lean right after the swap).
All the parts are new except the rifle. The rifle used to have standard Leupold rings with a Vari X III. Now it has an EGW picatinny 20 MOA base, Seekins 1" rings, and a Zeiss Conquest 6.5 x 20 x 50mm. Apparently, the problems lies either in the a) holes tapped into the receiver or b) the EGW base is off.
Any ideas/fixes from the gurus??? I hate to start buying bases till I find one, but I really hate to have a receiver who's holes are wrong.
Many thanks in advance, guys.
