I suggest you use a program like JBM. While the first time getting all the inputs done may be a bit daunting your reward will be
turret twist outputs in the form of MOA or Mil-Rad

one input that might be difficult is true barometric pressure that accompanies altitude. To help you along:

2000 27.80
3000 26.82
3500 26.33
4000 25.84
4500 25.37
5000 24.90
5500 24.43
6500 23.57
7500 22.71
8000 22.23
9000 21.27
9500 20.79
10,000 20.31

The is second column to right of distance will show you how much to twist the turret. Some of the amounts for MOA are not possible as the typical MOA turret in set in .25 increments. Simply round up or down to nearest increment.

You will need to know the velocity and TRUE BC of the bullet. If there are any discrepancies with the POI at distance IMO you are better off tweaking velocity than BC.
