I own 5 of the scopes you have. I have also shot with some of the best around with all different types of scopes used.
First, on the new nightforce scopes, they don't put a number value on the objective/paralax setting.
I don't know how to say this, but there just a number on the scope no matter who's scope you own. You adjust your paralax and focus. At 600 yards, my final adjustment might end up around 450 on the scope.
It was hard for me to understand, but that's the way it is.
I have shot with some of the best F class shooters around who all state the above.
Forget the numbers on the scope, get your paralax close, adjust your focus, readjust paralax, and final focus. Your objective is to get all the paralax out of your focus NO matter where the number falls.
It would help if you had someone very experienced with setting the scope help and explain what he is doing. Maybe there is a video online that will help.
Otherwise, you have one of the best scopes made!
PS: I found this video on YouTube, maybe it will give a better understanding. There were also several other videos on scope adjustments.
