Looking for a comprehensive study and/or information on head and tail winds. Yeah I searched and all that shit and could not find the google sh search engine thanks to the new format.

thanks all
 
I'm assuming you are speaking of reading proper left or right hold verses vertical differences due to head and or tail winds. Head and tail winds give virtually everyone headaches due to them not being perfectly straight on or straight away. they are moving your bullet either left or right of your target, although not to any degree full value like a cross wind would, and it is constantly changinig. I would much rather shoot at distance (600-1000) in a cross wind any day rather than a head or tail wind. You can plan and adjust for cross winds and fade in or out depending on pick ups and let offs. with head and or tail it requires much more vigilence on each shot and it is zig-zagging all the time. At 1000yds. it can zig-zag numerous times between you and the target. In short....I HATE TO SHOOT IN THEM!!!!!!
 
Exactly,

Head Winds & Tail Winds never are... they just bounce to either side giving you more left or right at any given moment than any vertical change.

Terrain will cause more vertical dispersion under windy conditions than what is considered a Head Wind / Tail Wind Effect...at the end of the day, without terrain to exaggerate the effect, you cannot hold the vertical component it is too small to worry about. Add in some terrain, and even a crosswind will cause a vertical dispersion. Worry about the cross wind component and not the vertical.

David Tubb has also done some extensive research on "dissimilar wind drift" which is incorporated into his reticle. This discusses the vertical changes caused by wind based on the direction of the rifle twist and the wind. So you want a rifle twist that works with the wind and not against it. He uses rifles that are both and left and right twist then chooses the one to compete with based on the wind direction.
 
Think of shooting in winds as being like sailing a boat in a current.

Sail upstream, arrive later. A longer time of flight results in greater drop.

Sail downstream, arrive sooner. A shorter time of flight results in less drop.

When folks start getting into the corkscrewies, they lose me.

One of the hardest truths for me to accept was understanding that the facts I know are often not the important ones. LL has it spot-on.

Depends on where in the flight path the river of wind hits the bullet.
Some day when you have the time, read the terrain and wind. Then take 5-6 smoke pots and set them up to a grand or better an just set back and watch. Do this often enough in hot and cold weather and you will get an idea on what you thought/think is happening vs what really happens. Now think about where the bullet flys, vs LOS from start to target.
 
Thanks for the info fellas. I was looking for info regarding changes in elevation adjustments versus windage. I will concur that head/tail winds are annoying when it comes to windage. Just looking for some concrete info regarding changed in vertical bullet impact.
 
To be honest, I have not had that much concern over changes in comeups in dealing with head or tail wind, no more than changes in temperature does. I shoot at one of the most finicky ranges in the country, so I'm told. Butner, N.C. with all the terrain changes it's known for tricky conditions. I usually set my scope according to my dope and let'er rip. It's the zig-zaging that drives you nuts!!
