When your rifle has been bore sighted, all you can expect is that it will hit paper. Fine adjustments must be made in order to zero. Bore sighting is for "ball park" only. When installing rings, I have found it very useful to use steel roundstock, snug it in, and then tighten the lower ring screws evenly and a little bit at a time. Once that is done, I remove the roundstock and install the scope onto the saddles, install the ring caps, and slowly and evenly snug down the rings alternating front to back. Once the scope is in but can still be moved, I position the scope for verticle and eye relief and then tighten the screws. Now it is time to bore sight. Once it has been boresighted, go to the range and set up a target at 25 yards. Fire one round. It should be on paper. If you are in the black, continue out to 100yds and zero. If you have to go near to end of adjustment, you will have to shim. I have found that aluminum soda cans work well for shims.
