.270 is a fine round...however, if ya like it...look at the .280. Its even better.
My money goes for the .308 or the '06.
Concur.
With a billion rounds and hundreds of millions of weapons produced and still in armories in these calibers, practicality dictates continued use of these calibers.
The .308 and .30-06 are close enough in ballistic terms that we are at "pick 'em". Prior engagements and logistical realities should decide the matter in favor of the .308 NATO round -- with allowances made for older .30-06 arsenal queens still in the possession of The People.
When I lived in Wyoming, I chose a .270 for my big game rifle--flat and fast.
