    Does anyone have a ballistic chart for the 6.5x47 lapua in the heavier bullets 139 or 140s. Just wondering how much they drop in inches and in fps out to about 800 yds

    That is a tough question when you didn't give us any data. Bullet weight and BC? Elevation? temperature? Velocity? etc.

    Go here and punch in your variables: JBM - Calculations - Trajectory


    one that will be hard to do is the elevation/ barometric pressure
    here are a few. I don't have any lower elevations I live at 2500 ft and never go down in elevation to shoot:
    Barometric pressure adjustments
    2500 27.32
    2550 27.07
    26.84 2600
    3000 26.82
    4000 25.84
    5000 24.90
    5500 24.43
    7500 22.71
    8000 22.23
