Everyone compares barrel life to 308. Everything I read says 308 is good for 5000 rounds of match grade accuracy and double that for hunting accuracy. Supposedly the 6.5 should be good for about 1/2 that.
I never see anyone say anything about 270 barrel. With similar bore diameters, and much more powder in a 270 I'd THINK a 270 should wear out sooner. But I've never seen any numbers on that.
