Felt recoil is unmeasurable boils down to personal or individualized. AKA; fit(rifle to shooter -stock design,etc)&/or mental.

Difference in weight with rifle, bullet and charges are measurablein terms offree recoil produced. Obvisouly if differences exist in these inputs it effects the output (recoil).

My experience has been when I shoulder a rifle that fits/feels good the rest takes care of itself. If the opposite happens I pleasantly hand it back and say next please!
