With a flight time of just over one second for a .308 at 1000 yards, the effect should be minimal to negligible to irrelevant, unless an inch or so one way or t’other matters...
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.
