No, this isn't a generic "which is better", this is looking for the experience of those who've used both.
I've owned 3 30-06s, and shot others, either Remington bolt actions or an M1 Garand. I've shot one 270, a Ruger #1.
I used to be an armchair fan of the 270, as something that can launch a not too light bullet pretty flat and work in everything an '06 will work in riflewise. In fact most modern guns chambered in 30-06 are also offered in 270 Win - Even the M1 Garand!
And one fellow wrote back in the day that he thought the 270 could effectively take any game on the continent. Well that's nice.
But what can a 270 do that a 30-06 can't? Though the trajectory may be more curved, does the 30-06 really have less range?
I knew all this but had the impression that the 270 had lower recoil. Well I never thought the Ruger #1 was a lightweight, and when it bit my shoulder, I just wondered WHY? The muzzle blast was greater than what I'd expect from an '06 too.
So I guess my question is if there's anything good about the 270 Win? Have folks fired it and 30-06 in nearly identical rifles and had better results than I did with the #1 vs the Remingtons? Or am I right to wonder why so many people use the 270 when the 308 and 30-06 are around?
