The process should be,
Read the wind, if you suck at it, use a wind meter and take that value and apply it to your rifle
The first number in your rifles' G1 BC is the wind speed to determine your rifles MPH, so if you are shooting a 6.5CM
.58 - .60, call it 6 MPH so work, only in multiples of 6 MPH Brackets
So, now you have that determined, what it tells us, 6 MPH =.6 Mils at 600 yards,
200 - .2
300 - .3
400 - .4
500 - .5
600 - .6
That is your wind hold, if you did you doped your rifle correctly your elevation should be good, 2 MOA of error correct, so it's all wind.
I have no idea your caliber, but go to the bullet's information and pull the first number in the G1
