    I like to get real world drop data every 50m out to 250, plus chrono data for the same day. I then tweak BC and or velocity as needed to match up all the points. With Shooter app for example, you can have multiple BC entries for different velocity ranges. Doing this you are essentially creating a custom drag curve through trial and error.
