Hmmm. Not to bust your bubble, but there's a lot of redundancy in that list. I'd be comfortable carrying any one of them anywhere in the lower 48.

My suggestion would be to either fill out the bottom end with a .204, .223, .22-250, or maybe a .243 - OR - fill out the top end with a .338, .375, etc.

Adding a .30-06 or .308 is just more of the same.
