Typically I would say 30/06 all day long over any "magnum" 30 cal. for what I hunt, and in fact the old legend is what I carry most of the time. But I've worked with a few 300 WSM's and geeze - they really behave themselves. It doesn't seem to take much at all to work up not a good, but a great load with them. If you shoot factory, go 30/06. If you handload, probably still a 30/06 - but a premium 165gr at 3,000 fps that shoots little bug hole groups all day long, in a short-action rifle (for those who care about that) with recoil that is not much different than an '06 sure makes the WSM an attractive option.
