Picked up a used Savage M11 in .223 with a 22 inch heavy barrel. It has a Nikon 4-12X40 Prostaff scope mounted on it. Got it for $350 off a guy at the range who is moving and did not want it anymore. It appears barely fired. I have two questions.

1.) Which model of the M11 is it?

2.) What is the twist rate, so I know what to feed it?

Thanks for any assistance.
