My experience is that in all cases the actual wind drift, especially at shorter ranges, is no where near what the ballistics calculators will tell you to expect.

That said, a calculator says that a 40 v-max .204 ruger bullet, mv 3900fps, will drift 13.6 inches at 200 yards in a 40mph crosswind. A 385gr Remington Core-Lokt Ultra 12ga slug at 1900 fps will drift 36.4 inches in that same wind.

Now, in all fairness, that's not a fair comarison because the cross section of the slug is HUGE compared to the v-max. The difference in same caliber bullets is much smaller.

110gr round nose 308 at 3000fps 38.7 inches, 220gr round nose at 2000fps, 31 inches
