I personally prefer the WSM .270. It's a great all around gun and will kill anything you shoot. Since you have decided on something else though, I would lean towards the 7 mm in a WSM. Either would be a fine choice, but that 7 mm mag. WSM is a sweet gun. Almost as sweet as my Browning .270 WSM. Even if you don't go with the WSM, it's still a great gun.
