You don't need a fancy bench rig to take the human element out of the equation. Place sandbags under the forend and under the butt stock. Make minor adjustments by squeezing the bag, or wiggle the rifle down. That makes your rifle steady. You will be able to see less or no movement of your reticle on the target. Then do everything as you normally do.
You can't fix stupid....however ignorance can be cured through education!
