Garrets 540 grain loads will get your attention in a hurry. If dealing with the same amout of ft.lbs of energy, the heavier bullets will always generate more recoil. Plug in the numbers to any recoil formula, rifle or hand gun, and this will always be true. It is simple physics. The heavier bullets will alway cuase recoil to be greater because you have to move a heavier object and rifle momentum is greater in the opposite direction, when pushing against something heavier.
