I'd grab an older Ruger M77 tang safety in 270 Win. off of Gunbroker.com. Bought one for my son many years ago when he turned 14. It has served him very well over the years, up to and including several beheaded bunnies and grouse, deer, bear and elk.
Now, if you said ok Gos. I'm putting you on a plane and dropping you off in the middle of the woods for a year and you only have one gun to live off of, it would be without any hesitation a 12 ga. Winchester pump shotgun with bird shot to slugs. It will truly do it all.
