Mule Deer: Here is a tip I learned 50 years ago this summer and have been adhering to it stringently!
DO NOT set-up in a Colony Varmint Hunting situation with the wind "90 degrees to the shooter" like you illustrate!
It is simply standard procedure for those in the know to set up with the wind either in your face or at your back - this negates much windage induced troubles.
I guess one could set-up in a Colony Varmint situation with the wind "exactly 90 degrees to the shooter" but long ago I learned the successful hit ratio (fun factor!) is greatly enhanced with positioning oneself so the the wind is as close to directly in your face or at your back as possible!
Try it - you'll like it!
Hold into the wind
