I hold it like I plan to shoot it in the field. I want to know how it reacts to a hunting hold.
I understand your purpose. However in 'group' shooting and trying to find out 'how accurate the rifle is, I try to eliminate human error as much as possible.
AFTER determining the accuracy of the rifle or load, THEN I shoot field/hunting positions.
edit to add: I intended to include this but forgot.
Even with an 8 mm RM and 200 or 220 gr bullets, I don't hold the forend. Most of the recoil is REARward. There is some muzzle jump but it's not a lot.
