I would say the 30-06 is better at rolling feral hogs with the first shot with the heavier bullets (165 and 180).
On deer, I don't think the 30-06 offers any useful difference over the .270s, 7mms or 6.5 mms.
I used to think I'd never want any more than a .243 to hunt anywhere in Texas. Until I started seeing feral hogs. Some are the size of my desk, and all of 'em are walking bullet traps.
