Re: Confusing Exbal Question
Sounds to me like you are having drag model and BC issues.
After you iron out all the other variables such as your scope height and such, take your real world data and go back to your program and try different drag models (G5, G7 ect.... and different BC numbers untill your program matches your real world results. This will be your drag function and BC you will use from now on.
Also it is REALLY important to input real air conditions during your tests. If you dont have a hand held wheather station, go to the web site below and select your closest air port. This will give you the closest data. Remember too when you use air port info to select the altitude youre at and the "area pressure" NOT station pressure.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
