Funny, for all the time I’ve spent researching & calculating long-range shooting, and all the references to Coriolis Effect I’ve seen, I don’t recall ever actually seeing a quantitative reference to it (a la “.308 at 1000m aiming due south, add 3cm left”).
Holdover, windage, velocity, etc discussions always mention numbers at some point. “But muh Coriolis!” doesn’t.
I suppose a picky sniper who enjoys mock self criticism might smirk at calling a head shot “a miss” shooting North at a terr, because point of aim was center of cranio-occipital cavity (between the eyes) and instead bullet struck left orbit...
All from failure to take Coriolis Effect into account...Tsk, tsk...At 1000 yds, I’ll count that a hit...Red mist is red mist!
That’s because unlike wind, angle or air pressure variations, Coriolis depends on both firer and target location on the earths surface and direction of fire....
It has varying effect from pole to equator and the declination angle of fire itself drives the equation.
