AB shows 6.4 for 9 o’clock wing and 4.8 for 3 o’clock 20mph for my 300wm    For right twist barrel wind from right pushes bullet left and up, and down and right for left wind.   Has todo with spin rate.  Seen it many times. 

Wouldn't it be more correct to say Right twist barrel wind pushes bullet left, and not down as much.
it does not push bullet up or down as much as left or right but it does move it enough to need to adjust elevation.  Enough to make over 6” different at 400 yards.  Granted that’s a 20mph wind but it does matter.    Brings a lot of truth to the ol saying garbage in garbage out.      This is why I love shooting in the crazy wind days.  It teaches you so much. 

We use to have a saying "strong wind brings out the Dopers",  :hello:

They were usually the only ones dedicated and who shoot even in windy or cold conditions,  :chuckle:
Only 2 defining forces sacrificed themselves for you:
The American Soldier and Jesus Christ. One died for your freedom, the other for your soul.

My rock,
He trains my hands for war and my fingers for battle.

If you shoot in rifle matches you don't get to pick the weather.  It's either compete or go home.
