Understated defensive rifle: suggestions?
Yo, rifle gurus ... Am looking for a basic rifle, a single rifle, for defensive uses when out in the country, for occasional light hunting (small game) at shorter ranges (< 250 yds), and for the home. Must be dead solid reliable, relatively simple to maintain, tolerant of various brands of ammo. By "understated" I mean non-AR, non-AK in appearance ... rather, something that wouldn't be out of place on a simple gun rack in the cab. Prefer auto-loading, but could accommodate bolt action if required.
I like the idea of a "ranch" rifle or carbine, but am open to alternatives. I'd consider up to a .30-06 or 7.62x39mm, and definitely prefer larger than .223. Prefer rifled ammo, though I would consider 9mm or .40 (ie the Ruger carbines). Understood on certain ammo availability, right now; forget that as an issue.
Am competent with smaller rifles, shotguns for skeet. Has been awhile since I've owned a small- to midsize rifle.
Suggestions on possible choices (make/model)?
