Have the same shoulder problems as you, from benchpresses at the gym & work, could never have the time off to fix. I shoot a Rem 700 LTR 308 cal. 20" brl. installed a brake to stay on target. I like shooting the rifle without pain. My kind of shooting is only benchrest for accuracy only, the rifle has weight, that will make the difference in recoil. Hope I helped in some way. Chris
