Hi,
All of the above . . . PLUS the addition of the venerable 30-30, 7mm-08 and the 308. Actually, you don't need a flat shootin' 7 mag down here, it tears up too much meat. The 270 will do quite well as a long range "field gun."
My main rifle (and my vote) is chambered in the flat shooting .270 and my back up rifle in the slightly harder hitting 30-06. These will both put 'em in the dirt fast.
For deep woods though, ya can't beat the 30-30 though, and lots of hunters I know grab theirs instead of their 30-06 or 270 when "going deep."
IN THE END . . . it's BULLET PLACEMENT that plants 'em best, and shooters who don't put the bullet exactly where its supposed to go lose plenty of deer . . . and thus create beliefs that certain calibers are better than others from within the group of calibers listed.
