The issue with a light/free recoil hold whether bench or prone is that the rifle movement has to be exact and level in it's movement during recoil. For this to happen, especially with recoil is that the rifle rest, front and rear, have to be parallel to the barrel during all movement of the rifle. The stock design has to have a flat bottomed butt, like the A5. This is manageable for bench shooting, and difficult in hunting conditions. A proper, and consistent hard hold can keep the stright rifle movement under control over a wider variety of shooting conditions. I use the same hard hold technique for both hunting and competition with no difference in accuracy but it took a while to build the muscle memory. For my best results I pull the stock with moderate/firm pressure into my shoulder, contact my cheek to the stock with very light pressure, and in the prone postition, keep my weak hand on the rear bag, with moderate forward pressure against the bipod. From any position I try to get my body behind the rifle as much as is possible.
