Hey geojanitor, What is that shootin stick set up?

A way to test it if it is changing POI or not is to shoot it both ways off of the sticks and the way you originally sighted it in at the farthest distance you would use the sticks.
Even if there is some POI change it may not be enough to be an issue at those distances for the game you are hunting.
What it ultimately does though is give you confidence of knowing what you and your rig is capable of from varying field rests at your max distances.
