Kinda the same opinion here, a fellow could hunt whitetails for a lifetime with either and never really see a difference...If most of the hunting is woods hunting and as you said, shots within 250 yards or so, I would probably go .308...If shots were over bean fields where you might want to reach out past 300, I would lean to a .270...
That being said, a .308 was used by snipers for years......
