I voted 300 win mag good ballistics, power, bullet selection, manageable rifle weight and recoil with or without a brake, not to expensive to load for, its popular reloading supplies always in stock, and not to little or to much for most situations.
I voted for the 338 RUM, it packs more energy than any of the smaller calibers to pretty much any distance, doesn't burn barrels as fast as the 300 RUM, doesn't cost as much to reload as the Lapua, comes very close to the Lapua in velocity & in a properly built rifle with a good break, kicks about like an '06. I don't mind packin ear plugs when I hunt, at most extended ranges you have plenty of time to get'em in before you take the shot IMO.
I voted for the 7rum. Just because it is as close to one I would chose. The 7Allen mag. or 284 Jazz would be my choice. High BC 189's and 200's available, excellent brass, and flat out performs! They can reach way way out there.
I am a fan of the 7mm's because of the High BC bullets available. I also have a friend who has many trips under his belt to New Zealand, Africa, and several other places. He has harvested alot of game in his life all over the world with a 7 rem mag.

I will take the -06 if parameters are not specified.
There is a bountious land and many sized critters, so for 99% of the time, the -06 would be more than up to the task, and ammo is plentiful. Ground Hogs to Moose if need be.
There are others on the list, in fact most that would be acceptable.
