I can no longer read the numbers in the input cells in that second pic.... All I can suggest is that you double check all the inputs.... Make sure you have the correct pellet weight, BC Model, BC, velocity, etc.etc. in each of the tabs.... Here is what I get with my ChairGun....

Pellet 14.3 gr, BC = 0.024, Vel. = 1058, Zero 40 yd. Scope Ht. 1.5", 10X.... ICAO Atmospheric Conditions.... Drop at range....

100 yd. = 15.97"

125 yd. = 32.52"

135 yd. = 36.76"

150 yd. = 57.37"

HTHs....
