Now you still have to call the wind, when it appears...which it will.
If you watch the mirage move through a spotting scope, even at 200 yrds with a mild 5-7 mph wind, full value or other wise, you`ll forget about spin drift.

Fun and interesting to talk about, but IME, application gets lost in the wind....or is it "Gone with the Wind"?

YMMV


This^^^^^

Here are results from the ballistics program for my 6 Creed at 500 yards. Spin drift is 1.13 inches at 500 yds. Adding only a 1 mph crosswind completely offsets the spin drift. I spend quite a bit of time shooting at long range steel and I can say with certainty I can’t read a 1 mph wind in hunting conditions.

The choice of bullet matters. Spin drift is a relatively small effect, but the ratio of spin drift vs. wind drift gets higher when the BC of your bullet increases, possibly to the point of no longer being lost in the noise.
