I do have a couple 6.8 AR's and a Model 70 in .223. Alot of my problem is I can't straighten my arms. I'm going to try one of these one handed off a rest and see how it goes.
Thanks for the tips and well wishes.
Sorry to hear this. As I edge into the Golden Years I too take note of my infirmities and adjust my shooting accordingly. If you don't mind my asking, what led to the wrecked shoulders, so I may act accordingly to forestall it happening to me?
