I'd stick with a big 7 personally. 7 mashburn, 7 Practical etc. You really have to push a 300 hard to compete with the 7mm. With that you have to deal with a lot more recoil and use heavier bullets in the 30 cal. That's the selling point of the 7mm. High bc pills with less recoil. It all depends on what you are looking for and how much you intend to shoot it I guess, but for a good 30 cal I'd go 300WBY before messing around with the Win mag.
