Re: Warm up your Ballistics Calculator!

Using a modified Pejsa spreadsheet, which has no accounting for Rh, coriolis, or spindrift:
750 = 12.3 -2.0
1015= 20.7 -2.9
1600= 49.3 -5.5
2200= 107.7 -9.6

    Re: Warm up your Ballistics Calculator!

    Reloader's Archive accounting for ALL variables listed:

    750 = 12.25 MOA drop/2.25 MOA windage

    1015 = 20.5 MOA drop/3.25 MOA windage

    1600 = 49.0 MOA drop/6.5 MOA windage

    2200 = 108.0 MOA drop/12.25 MOA windage

    It is notable that at 1600 yards the velocity is nearing the transonic zone and at 2200 yards it is way under at 755 FPS.

    Re: Warm up your Ballistics Calculator!

    Our "regular cell phone solution", I can't give you the exact numbers because the software automatically rounds to nearest 1/4 MOA click:


    Code:
    Range  	Elevation	Windage
    	correction	correction
    ----------------------------------
    750 	UP 12.0 MOA	Left 2.25 MOA
    1015	UP 20.25 MOA	Left 3.5 MOA
    1600	UP 49.0 MOA	Left 7.25 MOA
    2200	UP 111.75 MOA	Left 14.25 MOA
    ( using Bryan's table format as a template for clarity )

    Re: Warm up your Ballistics Calculator!

    Using Loadbase 3.0 Mobile this is what I came up with. Using spin drift and coriolis in the G7.

    750 yrds 12.1 up and 2.5 left 2136.5 fps

    1015 yrds 20.3 up and 3.6 left 1785.6 fps

    1600 yrds 49.4 up and 7.2 left 1140.4 fps

    2200 yrds 108.0 up and 12.0 left 876.1 fps

    Bryan, we're pretty close for the first 1600 yards. We have 0.9 moa = 20.7" difference at 2200 yards.

    My goodness, you and I are real close!!! 4.6" difference on windage at 2200
    yards. Not bad.
