I have had similar problems with ballistic calculators. Just like you, I have weather station and have gone to extremes to input as much data as possible. I've measured scope axis above bore, etc. Many of the factors do little to the final solution.
I wanted to know how to fix the firing solution or what else to tweak? I am having trouble finding extended distance ranges to shoot beyond 300 but even at that distance my calculated solution will request 2.1 MOA come ups. In reality I need to add an additional 1MOA. Other rifles are very similar.
And all the programs do the same math...Sierra Infinity or free calculators from BigGameInfo. All are plus or minus .5"
Do I really need to fudge the fps 200-300 so it fits? If so, what shakes out at 600 if you get it tweaked at 300?
