This nature of thread has come up before and one responder suggested the enviro shield shirt system. I bought it because I have a 50% tear in my rotator cuff. At first it was a bit uncomfortable but after a few months of bird hunting I recommend it to all who suffer shoulder problems. I was out sighting in some rifles the largest being a 257 and there was minimal felt recoil. There seems to be more recoil with my migratory shotgun where I'm using BB at 1550 fps but it saves my shoulder. Read about it and try it out. I highly recommend it.
