I didn't realize how old it was at first and mostly noticed the huge disparity on the velocities chosen to make the comparisons. The 270 Win velocities jive with what I have seen but most 6.5-284s will push a 140 at 2975 to 3000 with modern powders pretty easy.
270s don't have the appropriate twist rate to use decent bullets.
Discussion over.
Agreed. As soon as accuracy starts to diminish just a little the .270 WSM will get a faster twist barrel to stabilize the 170 Bergers... or chambered for 7mm WSM.
