"this however would have very little to do with the rifles and everything to do with the man behind the rifle."
It would have a LOT to do with the rifle as the design plays into it by allowing both high operating speed AND allowing for minimal disturbance of aim while operating the action.
If you have to regain not only your sight picture but also your position on the rifle because you had to shift while cycling the action, your going to give up accuracy, speed, or both.
That's not going to benefit just a trained rifleman, either. It's going to benefit anyone who has been shown the fundamentals of firing the gun.
