That said, for shots that a person (a sniper or long-distance shooter would take), I would consider the CE a much, much smaller effect than factors like wind or gravity.
And if you're a person that wants to be able to make a reasonable effort to hit targets beyond 1000 yards--just to satisfy your curiosity, I suppose you could attempt to apply the Coriolis "rules," but I think they're beyond the comprehension of most normal shooters. If you hit a target at these ranges, it's mostly luck; if you miss, there's more to blame than just the Coriolis Effect.
Wind is most certainly the hardest to predict and bad prediction would overwhelm other effects at distance.
Regarding the application of CE, I can simulate the effects on a computer, but wouldn’t attempt to calculate them on the range. I would let a Kestrel or other ballistics calculator include that for me, along with spin drift and all the other rifle/cartridge specific ballistics. If I haven’t dorked up the Kestrel inputs (garbage in, garbage out), then elevation is usually spot on and I can attribute any windage deviation to my own poor reading of winds.
