.308 is a lot easier to find right now. 300AAC hasn't been out long enough to hit the Walmarts or small town feed stores. Any able bodied person should have no problems carrying a 10lb rifle. On top of that you save less than a pound by switching from the predatAR .308 to a 16" DD .300blackout (7lb 12oz. vs 7lb 1oz.) Both will be around 10lbs loaded and scoped.
I kill hogs regularly with a 5.56 shooting 55gr ballistic tips, 64gr soft points, and 77gr OTM bullets. 5,56 would be plenty for hogs at semi close range. but the OP asked for a .308.
There is the RRA LAR-47 that is an AR that takes ak mags and shoots 7.62x39.
