Lots of people shooting 6.5CM and I've never heard it called a "barrel burner". I don't read the same articles you do. Do people complain about .243 Win burning barrels? Same powder capacity, smaller bore diameter.
I'm not worried about it, it will take a few years for me to fire that many rounds even if the estimate is accurate.

Good way of thinking. Guys get confused about barrel life. When a HP competitor talks about barrel life, he is saying that he may need a new barrel when his X count drops at 600, 800, 900, and 1000. We would get more of this 'barrel life' with the .308 if we went to a longer bullet at those ranges (except for Palma due to rules). The point is that the numbers that are given have two things in common. First, they range greatly and second, they normally concern long range and may be just fine for 300 and 500 for another five hundred or so rounds before they see a decay in scores at those ranges. Then guys may use the barrels in short range practice for another thousand rounds or so.
Yes, the 6.5 Creedmoor and .260 are not considered hard on barrels when compared to the various 6mm's.
No matter the caliber of bullet used, the more powder a guy uses, the higher the wear on the barrel. Thus .308's outlast 300 Magnums, 6.5 Creedmoor outlasts 6.5 / 284, 6 BR outlasts 6 X 47 etc.
