The recoil advantage goes to the 270, which often trumps a small advantage in ballistics.
If comparing apples to apples, one should compare the 170 berger and the 180 eld.
Nah, that would be too easy and make it seem like the 270 win treads too much on the heels of the 7mm rem mag....
Wait for JeffO to pull out the ballistic gak, we all so greatly appreciate..
Some people might think others like the feeling of smoke being blown up their azz...
