With a 30.06 bolt action for a single choice rifle, there is no peer. I know that sounds pompus, but..........
It covers all the bases (95gr to 220gr) from prairie dogs or self defense to moose with the multiple ammo weight choices available. I repeat available. It's available everywhere from Mullins, TX to Alaska.

Disclaimer: I hate these opinion things. I own many common calibers of rifle (.223, .243, .270, 30-30, .357, 7.62x39, .308, 300wsm, 45-70) and always grab one of my 30.06's cause it works every time. Maybe the way to put it is that you can't go wrong with a 30.06. With others, there are sometimes limitations.
Cheers.
