Are yoy buying three rifles or just buying one and want to choose betweent, 270, 280, 30-06, 7mm, 300 WSM, and the 300 WinMag? Between the 270 and 280 I would choose the 280 because you mentioned that you will maybe elk hunt. Wtih a 280 you can shoot 140 grains at deer and then shoot a 160 grain for the bigger stuff.
