Good Morning, las,
I have had 3 rotator cuff surgeries on my right shoulder, which is why I have had to give up big caliber rifles.
Yes, .308 Win is good for bison where I plan to hunt 'em. With a well-constructed 180 grain bullet, I should have no problem getting one in vitals.
Take care,
R
What, you didn't learn from the first one?....
My rotator cuff surgery was on the left shoulder- I learned not to fall off ladders. But it took throwing baggage for an airline to win back that last 10% or so, after a year of daily pain. It still is a little weak under heavy stress - so I can see how 3 such surgeries could cause recoil stress. Do consider my previously mentioned options on heavier caliber rifles however. They work - especially increased weight guns and super duper recoil pads,for your situation.
I'd use premium bullet in the .308 for bison.
Best wishes for a super hunt.
