I would probably reconsider the caliber choice. Id go with a 7mm rem mag or maybe 270wsm or 300 wsm. The 7mm wsm is kind of an oddball. Youd have a little trouble finding ammo. If your a handloader and thats what you want go for it, but it has no advantage over the 7mm rem mag. Seeing that the ultimate shadow is chamered in nothin but wsm's and if your set on that particular gun, id go with a 300 wsm.
