I know exactly where it will print at 100 and so if it's windy I can work out where it will hit at 200m or even 300m. But I'm using 165gn bullets which work best in my rifle and have an excellent BC. People using things like 110gn bullets in a 308W will find it very difficult to hold zero past 100m if a wind is blowing. My load has been chronographed at 2,750fps 2m from the muzzle.

Hey HS, i'm using 165gr SGK in my .308 at similar velocities and my calculator says for a 1.5" high zero at 100m it's 1" low at 200m, is your calculator/real world result due to higher BC bullets or errors in my calculator?

you say yours are high BC, just wondering what bullet you're using

MPBR's a good simple way to do it.

No obsessing over your ballistics tables :lol:
