I'd say the 200 extra fps that the 270 WSM offers up over the 270 Win is significantly more advantages than the the slight difference in BC between the 7mm and 270 projectiles....at long but not extreme range. Remember you were the one that said the 200 fps meant nothing but now you're saying the slight BC difference is enough to significantly seperate the 7 and 270WSMs.? It takes a long distance for the BC advantage to show up in a 180 bullet in a 7mm. It eventually does but speed trumps BC for a lot of yards.
