It's fine that it needs to be done, but what causes the delta between the math and the actual arc of the bullet?
You have to verify to be sure that the numbers are correct, After all it is only a formula and
The cause for the delta is normally that the listed BCs are effected by velocity,twist rates, ETc
and are normally not correct from the manufacture.
You dont have to check every distance, but I would recommend at least two(Middle distance and
the max distance to be shot.
It does not matter what the BC and drop is, what matters most is the accuracy of the drop chart !
