Actually I just compared the balistics in the same weights and types of round. The 270WSM beats the 7 Mag in terms of fps and foot pounds of energy along with trajectory and wind drift naturally. Now if 270 WSM were more widely available and less expensive then 7mm Rem Mag, then it would be the logical choice.
Only if you are stuck shooting factory ammo, and choose to believe the MV claims they are making to sell the shorties!
