I went 6.5prc for my all around gun. a 140-150g class bullet in the boiler room of anything huntable in north america will do the trick.
I built a 300wm for bear and elk, but its never been shot. Ill probably sell some parts off of it and find a cheaper caliber to replace the barrel to turn it into a range toy. no reason to pack around a big magnum to me with modern bullet construction being what it is.
