Conny I am sorry, but you are mistaken as well.
First lets separate felt recoil from actual recoil gun produces.
Actual recoil gun produces is determined from two things only, weight of shot or bullet and velocity when it leaves the muzzle period. Any gun shooting a 1oz slug @ 1800FPS will produce the exact same actual recoil.
Now felt recoil is determined how well the gun distributes or absorbs the actual recoil before it gets to your shoulder. There are a lot of things that can determine that. Weight of the gun, action of the gun, and probably the biggest is the recoil pad.
