RE: Which caliber would you pick?
Of those listed the 7mm-08 is my pick for Southeastern whitetails. Mild recoil yet a relatively flat shooting round and hot death on deer. A 140 grain bullet from a 7mm-08 is close to perfect for southern whitetails. An excellent caliber whose popularity is growing in leaps and bounds mostly because of dads who originally buy it for their kids then end up using it as much or more than their kids.
