How much rearward pressure are you applying with your shooting hand? Also how solid is the rear bag you are using?
Ending up 1 mil high indicates the butt of the stock is dropping during recoil, that has some to do with the rear bag, but also the rifle to shoulder connection. I try to get the butt of the rifle a little higher in my shoulder for that reason. That can mean raising the butt pad if it is adjustable, or simply raising the whole rifle. Holding the rifle to the rear will also aid in not allowing the butt to shift under recoil.
Also, it appears that you are “dipping” your right shoulder down to the gun. This indicates you are in too low of a prone position. I would raise the bipod a notch or two until your shoulders are level.

This second is just before you drop into position, and it more of what you are after as far as even shoulders/arms

The rifle also seems to be pointed slight to the right of where your body is pointing, but that could just be the camera.
