What holding the forend/scope/barrel does is compensate for poor body position and poor stock design. The rifle is recoiling up and to the right (for a RH shooting) due to the barrel being above the top edge of the butt, and exaggerated by how most position themselves behind the rifle. The lighter the rifle, the more recoil, the more pronounced it is.
An extremely light rifle with a negative comb (top of the butt pad above centerline of barrel) and a vertical grip, with a straight and neutral body position with no lateral deviation will recoil nearly straight back and does not need any tricks to make it work.
Tikka T3x has one of the better factory stock designs, which while not a negative comb, is at least straight, and with the inclusion of the vertical grip can be shot very well with a traditional hold. I.E.- shooting hand on grip, support hand under stock squeezing rear bag.
Easiest done prone. Get straight behind the rifle with one continuous straight line from muzzle, butt pad, eye, shoulder, right hip, inside of right leg. Recoil pad deep in shoulder pocket. Shooting hand bottom three fingers hook and pull grip into shoulder. Fingers do not wrap, or torque. Thumb nuetral.
This hold can be consistently replicated in the field and from almost all positions. Most “tricks” with light rifles can not.
Here's the thread I started on the same subject, and the above is the best advice I received. https://www.rokslide.com/forums/threads/shooting-light-ultralight-rifles.140393/#post-1346512
