This location the mirage looked like it was flowing from left to right like a fast running creek . I dialed 1 MOA left windage at this spot.
You are right about the surrounding wind I held up the kestrel 3500 and turned it slowly in every direction and it didnt move at all, but when I looked through the scope the mirage told a different story....
I relocated the target before we left , it is set up at 1000 yards now. I will be ready next time . I have a bI-pod should I use sand bags under the rear of the stock ? while shooting in the truck bed ?
Watch the tossles on the top of the stalks carefully. My bet is you see some swirl tha you cannot detect from your location. The convection causes water vapor to rise rapidly and thenit disperses very quickly to equal whatever the RH is in air. Think of thousands of little boat wakes just above the the corn. That's the water vapor exiting the stalks. The swirl above is that vapor dispersing above that level.
As for real bags. I'd use anything I could find to help improve steadiness be it bags, rear monopod or anything else I could utilize.
Remember to that at long range your trigger and breathing control or lack thereof can crate pretty large errors.
Len into it, relax and let it happen.
I go through kind of a mental relaxation exercise everytime I get ready to pull the trigger and basically other than leaning into the rifle I want my entire body limp when the round goes off.
