For very long shots, is it possible to convert the horizontal drift components of the Coriolis Effect and Spin drift into one single wind drift component that can be added to or subtracted from the measured field wind value? If so this would be a quick and simple way to include these components without the long drawn out process of calculating these as separate values for a particular shot. Example. Say you are shooting at 1200 yards with a 338 edge and 300 grain SMK @ 2800 fps with a right hand twist 1;10 barrel, with a light wind measured at 3 mph from 3 or 9 o'clock. Could you add or subtract, say a 1 or 2 mph wind value to compensate for the Coriolis effect and Spin Drift. Or is this a too simplistic way of doing things? In my area I have worked out that the Coriolis Effect is equal to about a 0.4 mph right to left wind and my spin drift value is about equal to a 1.5 mph wind to the right at 1000 yards.
