I had the same question a while back but decided to go with the 7RUM. I think Remington will offer more factory choices with premium bullets, and weights. I don't reload, so I felt the 7RUM will be a better choise down the road. Looking at the balistics, the 7RUM holds a minimal edge as far as speed and energy, to small of a difference to use as the deciding factor. I really can't comment on the accuracy of the STW, but my Remington 700 can usually print an inch or less pattern at 100 yards using factory 160gr Nosler Partitions.
