Not sure if people believe me or not but the rotator cuff hurts me as bad as hurt knees or back.... I couldn't even pick up a coke cane off the coffee table while laying on the couch.... It really hurt... Physical therapy helped me a lot but now twenty years later I still try and be real careful with it... It's one of those things I feel bad about when someone tells me it happened to them because I know it hurts...If you stock LOP allows, put a Protector brick style sandbag behind the stock butt and your shoulder.
