[QUOTE="Bullet bumper, post: 666422, member: 17844"] Something funny going on . Vortex says 65 MOA total elevation adjustment 32.5 MOA below the center . The 178 A max at 2650 sighted at 100 yards would need around 39 MOA of elevation at sea level at 1000 yards . With 20 MOA on the rail that would leave only around 19 MOA to put on the scope . I agree with LouBoyd the base may not be tapered at all or tapered the wrong way . If you measure the length , height at the front and back from the top to where it sits on the action in Imperial I can calculate the taper angle . For a 6 inch long rail it should be .035 diffrence between front and back. For a 7 inch .041 diffrenece , plus and minus a thou or two as not all rails are exactly the correct MOA. [/QUOTE]
