Were I to take up a "long range" target game, I would not choose either the .270 or the -06 ..... I'd want somthing more efficient that would not beat the hell out of me on the bench......
While I agree with most of what Jimbob said, I disagree that you have to suffer the above (excepting you have a collector 270 or 30-06 of some type that you do not want to mess with, i.e. Sako 270, 1903 that's vintage Pre 64 Winchester etc).
That said, my brother tamed his 7mm with a Limb Saver.
I won't claim to be an expert, but I have shot the 375 H&H as well as the 338 Winchester Magnum.
Of all those, the 7mm Remington Mag is the nastiest to shoot. I think you have to get into the .40 caliber and above to be worse than that).
If a Limb Save can tame a 7mm rem mag, then it will turn a 270 or an 06 shooter into a friendly house kitty.
No disagreement that its really a matter of choice as to what the mission profile is and what works a bit better where.
One gun battery and you are going to shoot anything from moose to Sitka Blacktail and you may have a bear encounter , then a 30-06 simply cannot be beat.
On the other hand, if you are Elk size and lower and never plan on anything bigger, then a 270 is more than adequate.
And if you are out at 500 yards, I don't see any difference between 44 inch hold and a 50 inch hold. Too many other factors are going to play into that shot as it is a field shot not a bench rest shot (even if its a supported shot).
If you like the 270 (and I love it) then go for it. The only thing its shy of is the wider capability that the 06 has and if you don't need it there is some advantages that help in its area of capability.
Whatever the choice, both are great, enjoy it!
