Thread: Adjusting MV and BC to match trajectory

Not sure I follow Andy? Perhaps you or Gibo would be able to advise how MV and BC could be adjusted from observed trajectory data if the scope calibration is not known? The only way I can think of is to leave the scope set at the chosen zero and shoot at a very tall target that records shots 2-3 metres below the point of aim.
Scope turret calibration should not be assumed. It was not so long ago that I measured this on two top-end scopes and both had the elevation running at 71% of the dial setting across the full adjustment.
