1. First, the 308 comes close but TODAY the 06 can out do it especially with our newer powders.
2. I would NOT say any one would fill your bill. > "but can't think of one cartridge that works better as an all-around option."
3. IMO and for MY use & possible hunts in the future......
I'd take a 7 Rem Mag. There are plenty of GOOD bullet choices for the caliber LIKE the 30 Cal.
*** I like the 7s flatter trajectory *** THAT is the only reason. ! Dead is Dead, but flattER is better AFAIC.

7 MM Mag 160 Accu Bond @ 3000 FPS sighted at 200 is -.6.4" @ 300 Yds and 36.9" @ 500
30 06 165 Accu Bond @ 2850FPS sighted at 200 is -7.2" @ 300 Yds and 43.9" @ 500
For all practical proposes the is no difference trajectory, unless you see and hold alot steadier than I do. I'm however not a twister nor a long range hunter, fancy myself as a hunter.
