Entropy, you asked if there is any other reason beside recoil reduction to buy a slip on limb-saver. Since you have solved your recoil problem by holding your rifle correctly there would be none that I know of. If your rifle is fitting you correctly and you already have a recoil pad on your rifle, adding an extra half inch to the length of your butt stock with the limb-saver could even be detrimental to the fit of your rifle.
