Thanks guys. I was beginning to think like an archer which is the opposite. I am 2" high and 2" left at 25 yards. What you are saying is leave it 2" high at 25 yardsand just move it left. That should put me close at 100 yards?

By the way, I was told by someone that if you sight in zero at 25 yards it should also be zeroed at 100. Theory being that the bullet hasnt had time to rise at 25 yards and will rise then fall at 100 yards. Is this an old wives tell?
