I would choose the Rock River .308, of the choices you posted. I have and had many accurate bolt guns, but love shooting semi-autos more. The RRA will deliver bolt gun accuracy and the .308 is more than adequate for North American deer/Elk out to 300 yards.
Some of these post are hilarious in their silliness...
Obviously, you have very little “Bolt gun” experience.
If what you said were true, then the best shooters at Camp Perry would surely be using them. But last time I checked, about all you would get from a claim like that on the range at Camp Perry, would be uncontrollable laughing.
Thanks. I’m enjoying some of these answers.
