Re: Wildcats and the Kahn at 1 mile plus....
Beachball!!! I've been using an orange, it sure would have been a lot easier in the earlier "just figuring this out days" to have used a larger "earth". DUH!! on my part.
You can still run your/a test of sorts (as long as the wind cooperates). Have a shooter-to-target bearing of 000 true or 180 true for a series then switch to bearing 090 true or 270 true. On a theoretical target I believe we'd observe a right shifted group for the 000 and/or 180 and a high or low only group for the 090 and/or 270. Real world target results could/would vary but it might be nice to try. If the thing (experiment) worked out you'd have your empirical Coriolis deflection at both extremes. We'd need the latitude coordinate for the shot(s), both shooter and target so GPS fix would be good, elevation is also needed so we can calculate incline fire angle. Oh!, and we need to turn off the wind for the duration of the experiment.
