Great, thanks again for the help and insights. I'm looking forward to getting out for the actual hunt and then continuing to work with the gun sights.

Does anyone have experience with sighting your gun at higher temps and lower elevation than your hunt? What can I expect for change in performance when I get to the Mtn. I sighted at 2800 ft in 65 degree weather. I will be hunting from 7-9000 ft in temps that will likely range from 15-45 degrees.
