I mounted a Vortex 6.5-20 Viper on a 223 12BVSS using Burris signature rrings with inserts. Visual boresight was dead on with scope at 25 yards. Looked same at 50 yards. Took gun to range and POI was 10 inches high and 3 right at 25 yards! Tried different ammo and double checked all screws. No effect, back to house. I used the 10 moa inserts to offset difference to help save adjustment on scope. Checked boresight again and still looked zero. Shot rifle and still had about same POI. I adjusted scope to bullseye, backed off to 50 yards and tried again. Ran out of adjustment and still 2.5 inches high. Required another inch of horizontal to zero. At 100 yards horizontal is good, vertical about 5 inches high. Pulled bolt and boresighted, bore on target, scope is 3 feet high and a foot right???
Is the scope bad? Bad rings or bases. Or is it in the rifle? Ive never seen a boresight look that good and POI be so far off. Fairly disgusted at this point. AWESOME grouping, just too far off.
Suggestions?
