I'd go with something like a 270 or 30/06 that is relatively inexpensive to shoot if you are not a handloader, and then practice like hell on being able to shoot quickly and accurately from standing, sitting and kneeling positions. If you are like most, you are way overthinking what rifle to use and way UNDERTHINKING being able to hit a pie plate size area at 300 yards quickly.

This�EXACTLY
And you can improve on the BAR by getting something with a bolt handle�.
