[QUOTE="BrentM, post: 1579308, member: 61747"] Like others have said, it can be a cumulative effective. Scope tracking might be off slightly, zero range may be off slightly, scope height factor might be off. Since the impact is low by the exact same amount but the dial up is consistent for the range I'd consider a tracking test and verifying scope height to the center of the turret to the bore line. If you use the ring center to bore its usually close enough but worth a check. You may also want to double check natural scope alignment. For example if you are zeroing off a bench and then shoot the long ranges prone the alignment can be off slightly. In addition to that I have seen bench rest velocities be a tad higher than free recoil off the ground. [/QUOTE]
