The 30-06 is hard to beat, even though I start to think that I should own a .223 and replace all my other calibers with that little number :mrgreen:
Honestly, I do'nt see any real difference between those two fine calibers on game, the 06 and the 270, and still favor the 06 because of the versatility and availability of ammo and reloading componenets for that caliber everywhere.
Most of my medium and big game is shoot with various 30-06, as well as a number of grouse with slow velocity, 110 grain fmj bullets, and continue to do so, in the future.
Comparing those two calibers are somewhat boring.
