.300 WM.
That said, I have two .30-06's and wouldn't hesitate at ranges under 500 yards.
The .300 is just more authoritative. At 450 yards it will ahve about the same thump as a .30-06 at 300-325.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
A good .30-06 is a 99% solution.
