.257 Wby with the Accubond would be an ideal load for large Mulie's in open country. The 7MM really doesn't need a bullet as tough as the Scirocco for deer - I would also opt for a Ballistic Tip with this rig. One of my family members uses a 7 Mag with Scirocco's. They are a pretty good elk bullet in this caliber, but a bit of overkill for deer.
