At 1000 yards there is 5.1MOA of elevation difference..
Wondering if any of you have done any real world test's comparing the two drag models?
Real world testing to me means actually firing at different distances. (100 yards to 1000yards)
and comparing the results with calculated drop tables using the G1 model and the G7 model.
Without exception the G7 model was closest to actual.
If you use a spitzer flat base the Gi is close because it closely matches the G1 Model. But for the
secant ogive boat tail bullets the G7 is the one to use.
Just what I have found.
