With my bad left shoulder, a pump is the only thing I can really work well. I have Arthritis in it and have trouble getting the gun up and down from that shoulder. I can work the pump well though because I am right handed but have no right eye.(Lost it in a construction accident). I can't work a left hand bolt very well any more because there is no strenght in that arm when I raise it to that level.I can work a right hand bolt by reaching accross if I am shooting off a bench or bi-pod to support the weight of the rifle. Its hell to get old and beat-up. I am not about to give up shooting and hunting until there is just no way to do it any more.
