Note how as the range to a deer increases, so does wind drift. And remember, wind drift is even more magnified in a 15 to 30 mph crosswind. Out to 200 yards in a 10 mph crosswind, you really don’t need to compensate, but when shooting at a target or an animal that is 250 to 300 yards away, you should hold “into the wind” a bit. Note that wind drift-wise, the .243, .308 and .30-06 are nearly identical…the .280 is the worst at bucking the wind.
