For all around "1 gun" North Amerrica Hunting Rifle.
- Any Quality Sporter i.e.. Rem700,Win 70, Ruger77 etc, topped with a good Quality 3.5X10 etc.. Scope, chambered in one of the two North American Magnum calibers that have stood the test of time everywhere.
7mm Remington Magnum or .300 Winchester Magnum. Any other new wonder magnum is a waste of Ammo money unless you reload, just a new and improved version of what already works and dosen't need to be changed.
Several mentioned the .30-'06 ,and unless you are a excellent marksman who can squeeze everything out of the above mentioned Magnums, then the '06 will do everything you need up to Elk ,Moose.
With the Premium factory loadings today for this venerable caliber, it has got a new lease on life. 30 to 40 years ago if you didn't reload the .30-06 , it was just a long action .308 Winchester.
This is very generalizing, but I will guarantee you, either one of the two will do what you need anyday of the week and twice on Sunday.
