Data not matching shooting

Just thought of something else. Could be vertical wind. Were these shots in rapid succession or spread out over time? Have you repeated the experiment?

Well, the question arises as to the reliability of the BC value for the bullet.

Over a Mil difference between calculated and observed is huge . For the calculated numbers to be off that much the inputs to the program would need to be totally screwed . Box test the scope in a large increment , like 10 Mils plus , small 1 or 2 Mil box's aren't big enough to show a trend at close range . Those scopes don't have the best reputation for reliability .

Run it up here and we will put it in the test jig.
