[QUOTE="cdoubleu, post: 287482, member: 18034"] Head and tail wind are insignificant in most drop compensation. To bring it into perspective, the change in velocity through the mass of air is generally less than the velocity spread of your ammunition. (15mph=22fps). Even with a ~20fps difference in bullet velocity, vertical stringing is pretty small out to 1000yds, probably considerably smaller than most will be able to shoot given skill and equipment. Unless you have a real laser of a rifle and the ability to stack bullets at 1000yds in world record size groups, you will probably be chasing a unicorn trying to adjust for head/tail wind. But if you must, bullet impact will be lower in a head wind and the converse is true for a tail wind. [/QUOTE]
