Can MV be reliably estimated using load data and bullet drop?
My specs are:
308 win
26" 1 in 10 barrel
178 amax
42.3 grains 8208xbr
750' above sea level
80 degrees F
75% humidity
30" Hg
100 Yd. zero
8.5 MOA drop at 500 Yards
I don't have a chrono and would like to know if this load will still be supersonic at 1000
Thanks
