[QUOTE="Hunter15, post: 994446, member: 46673"] Good idea. To asnwer your first question my ES is 13 Fps. Below I will supply all program inputs. Muzzle Velocity= 2840 Fps Zero Rnage= 100 yds Sight Height= 1.9" Click Value= 0.25" Bullet Mass= 250 GR (.338 Sierra MatchKing) BC= .587 G1 Temp When Zeroed= 73 degrees Pressure WHen Zeroed= 28.85 Angle When Zeroed= 0 degrees Altitude When Zeroed= 0 (because local absolute pressure was used from Kestrel) Inputs once at range... Range= 818 yds Temp= 61 degrees Pressure= 28.72 Angle= -1 degrees Wind Speed= 5mph Wind Direction= 9 oclock Altitude= 0 (because local absolute pressure was used from Kestrel) Program outputs... 170.2" of drop = 19.9MOA= 79 clicks to obtain an actual drop at 818 yds I had to adjust dial to 18.0 MOA The gun shoots great from 100 yds all the way out to 818 but I cannot get the program outputs to match reality.
