I think bigcountry pretty much nailed that one. My Browning .223 is my go-to rifle. In the accuracy department, it does exceptionally well with a variety of ammo. The trigger is great for a factory gun.
Any of the calibers you mentioned are excellent hunting cartridges. My personal preference leans toward a .270, but I don't see myself hunting anything bigger than medium-sized game in the near future and maybe once in my lifetime going on an elk hunt. If your hunting something bigger, the .30-06 is hard to beat.
I mean you don't see too many people building thier custom on a browning action.
Why build a custom when you can buy a Browning?
