Have you taken a peek at the Savage Hog Hunter in .308? That sounds like a pretty darn good way to go to me. .308 ammunition ought to be just as plentiful, of not more so, than the .270. Plus, in my mind, it might be just a tad more flexible with bullet weights afforded to it. And, there's no doubting the .308's accuracy potential and hunting abilities. Not saying anyone has doubted the .270's, just saying the .308 has been around a while as well.
The rifle has sights, a threaded bbl (so you can play with it later with accessories if you like), and I believe a 4+1 capacity.
These folks are out of stock at the moment, but the link does give a photo and some details.
