i would go with a 308 loaded with 160gr or heavier premium bullets for moose and elk. Then load it for everything smaller with some 150 softies. I have shot 308 for years it is my go to caliber. My grandad's gun has taken most game in north america in his hands with 150 grain remington ammo and it still shoots great. Even with the 168's it doesn't knock me in the dirt or the face like my 7mm rem mag did.
