In other words, about average for 'AM Shooting Journal'.

Talk to some expert artillerymen or folks at NASA charged with computing the trajectories of rocket launches.
No, man - it's a real thing for ultra-long distance shooting - more than I will ever do with my weapons, but for some who can reach out there, it's a consideration.
While this is true, it is pretty much irrelevant for most shooting, long range included.
In fat, coreolis is much more complicated, who shoots in a cardinal direction? Imagine the offset if you shoot at say, 37 deg magnetic at a latitude of 42 deg?
Also, one must include more apparent ballistic influences such as spin drift, aerodynamic jump and precession, manges effect etc.
That’s why one shot hits at unknown distance on field fire ranges seldom result in one shot hits past 600 yard or so. ( unless the target is a barn door).
Or malarkey.
