I voted .270 Win. Propbaly the impact of Jack O'Connor's writings on an impressionable young shooter.
But what is really interesting is the closeness of the vote. There really is nothing between them and at the end of the day it boils down to personal preference.
Another interesting point though is that the .280 Rem must shoot a heavier bullet to equal, far less surpass, the ballistics of the .270 Win. The proper comparison is BC and SD not weight when comparing cartridges with differing bore size. Even when the diffrence is only 0.007". Or else agruments are based on rubbery figures or reasoning.
