Hope you heal up quickly. I would brake a rifle with a JP brake and go hunt. A few shots I would think would go un noticed.
All this makes me a bit uneasy. A few weeks back I lifted something to heavy above my shoulders. (sometimes I still think I am 30
) Anyway I felt something in my left shoulder grind or tear. The pain in it the next few days kept my arm below my head. It has gotten better, but still sore. I am using it with care as I work, and waiting for it to heal on it's own. I hope!!
PS, If needed, don't over look a 6br with an 8 twist and a 107 SMK or a 105 Berger. Recoil is null and a reasonably placed bullet would easily smoke your sheep.
