Yea i over looked it but you said prone yea prone hurts a bit more. you might try getting a SVL recoil pad I put one on my turkey shotgun I shoot a 3.5 inch federal premium hi velocity pushes 2 ounces of shot at 1300 fps out of my 7 lb shotgun has a recoil equivalence to a 416 rigby. The SVL (sims vibration labratory) recoil pad reduced the felt recoil to about that of a 30-06's recoil. they are great heres a link
