I was hunting last week in conditions that often had me trying to calculate for cross wind drift.

Is there a good rule of thumb for windage drift when shooting across the wind? Most of the calculations that I can find are for rifle bullets which have a much smaller cross section, are going faster and shooting further.

For example, I was taught for 30.06 the rule was 2 inches per 10 mph of cross wind. 4 at 200 yards, 7 at 300 yards, 11 at 400 yards, etc. Double for 20 mph, double again for 30 mph. Go home at 40 mph.
