I'd be inclined to shy away from a magazine fed .308 and stick with a big caliber bolt or lever gun. I've always been enamored by the .45-70 brush guns and even entertained the thought of indulging in a Wild West Guns Co-Pilot. Since the WWG TV show, prices have increased to ~ $3K for one of the take-downs, so that dream has gone up in smoke. For a fraction of that, I'd search out a vintage Marlin lever action in .45-70 or even .444 for bear, and leave the mag fed .308 for some other task.
