richard, basic geometry...
by moving the forend hand rearward...
you are increasing the angle of the barrels...
thus, making the gun shoot higher...
conversely, by moving the forend hand forward...
you are reducing the angle of the barrels...
thus, making the gun shot lower...
try it...
That is utter nonsense, and ignores the real reason that it can change POI.
What you are saying is that the hand position overrides the brain-to-muscle signals.
I could prove that to you on my 4' X 4' patterning plate, but you probably wouldn't acknowledge it if it hit you between the eyes.
