Great suggestions!! All are solid--

I have used 300 mags for most hunting with good results.
It is a great all rounder and delivers power and accuracy in bunches.

The more I think-(my wife says that can be dangerous)-
How about taking the 30.06 and 338 WM because various loads have the same trajectory and I would take one back up scope for failures/maintenance(I detest pulling well zeroed scopes of good rifles)? The scope would be zeroed for BOTH rifles.Of course depending on the animal this can limit you to 200 yds or less with the 30.06 when trying to deliver adequate energy and penetration.

Other reasonable suggestions?
