I gotta go 7-08. If you lived back east, and a tag for elk was not an every year possibility, I would go 6.5. But the heavier bullets you can use in a 7-08 would make more sense on a black timber hunt.

But I killed a cow elk last year with a 120 Gr Nosler mono out of a .260, and it was DRT. So if you go with the Creed it is certainly capable.
