Bob, the problem at the range is that you have to shoot from their bench. You can't change the seat to bench top height and it was set up for average people, not guys who are 6'4. So I end up hunched over the rifle and cheek weld is certainly not ideal.

However, the parallax issue simply means that the target and reticle image planes are not aligned. A scope cannot accomplish its intended purpose as an aiming device if the point of aim moves 2" in any direction if you move your eye relative to the eyepiece. When a $150 scope is properly adjusted, I see no reason why a $500+ scope should not be. If the parallax is correctly set for 100 yards, it is relatively simple to shoot good groups if the rest of the equipment is in order.
