Hello all. This afternoon I mounted my 8x32 burris on my savage with the 30mm burris signature rings and the dovetail bases. Knowing my 223 has a bunch of drop at 600 yards and beyond I planned to use the +10 insert in the rear and the -10 insert in the front. The problem was it took these inserts and a .011" shim behind the rear base just to get the scope zeroed on the bushnell bore sighter!?! The windage was not far off at all. This was after I tried the "0" inserts and found the crosshairs about 12" high according to the boresighter. Any ides as to what is going on would be very helpfull as I am kind confused at the moment. Could things have been this far off or should I be looking for another problem? I also swapped base locations thinking this could be the culprit but the change was very slight. Any ideas?? Thanks, Cdog.
