Shooting off of the hood could jut as easily be responsible since you can't really lean in and drive the rifle without also moving the truck.
You also get some swirling winds above a corn field that you will not feel from the hill above it due to the flow of water vapor out of the ground through the corn and into the air.
Also your shooting station was pretty well protected from any wind that might have been swirling around the corn field due to the tree row so you would not have felt or even noticed a very slight wind between you and the target.
Nest time look at the tops of the stalks very carefully and see if you can detect any motion due to wind.
The pic of the rifle and shooting position is of the 813 yard location .
I am a carpenter so I can build exactly what you guys are talking about
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 ?
