I have a Douglas in 7 saum that is one of if not my most accurate rifle, if I really concentrate and pay attention to what I'm doing I can wring .25" groups out of it at 100 yds, unfortunately I ain't always that good
I also have a couple of Pac Nor barrels that I have no complaints with, they don't group as well as the Douglas, but I suspect that has more to do with rifle weight and loads used than barrel quality.
Bottom line is any of the top barrel makers will work just fine for ya. As for the calibers you listed, I doubt there is 150fps diffence from fastest to slowest with the same bullet weight. I picked the saum because the case is .100 shorter than the wsm with a longer neck and I thought it was a little better fit in a SA with heavy bullets. But heck just pick one and bang away.
