I've owned both, and currently of the two only own the 270 WCF. IMHO the WSM isn't worth all the hype. You won't notice a hint of difference on game between either round, and you will find 270WCF ammo pretty much anywhere - was at my local gunstore this morning, and the only WSM ammo they had was 3 boxes of 300WSM and no 270WSM. They had a shelf of both 270WCF and 300WM and lots of variety in both. No WSM's of any caliber at either Crappy Tire or Wally World today.
