Default RE: Wind, bullets and trajectory.

Wind drift is determined by the shape of the bullet not by a bullets weight.From the sierra second edition loading manual;
.308" -165gr spitzer boattail 2800fps muzzlevelocity-30mph wind-
100 yards-2.09" 200yards-8.64"
.308" -180gr round nose 2800fps muzzlevelocity-30mph wind-
100yards-3.83" 200yards-16.39"
