I just got my Kestrel Sportsman finally. I am trying to tune the device to my dope. I can get the dope to align (using G7) until I get to 700yds and beyond. I've tried adjusting the MV but as the numbers get closer outside of 700yds, the shorter ranges start to deviate. Is there a particular variable that will affect the distant end of the curve more than the near end? I'm shooting a Tikka Tac A1 in 6.5 CM and using Hornady Factory ammo 147 ELD-M. Thanks in advance
