Heating the barrel up too much without cool-down time, not properly cleaning, and loading to the max edge of the envelope of ANY cartridge will do more to erode a barrel. Throwing stones at specific calibers using urban legend and lore isn't really fair to those rounds.
Yes, I used up a 6mm PPC that's no longer useful for matches, but it took LOTS of shooting to do it. And it STILL shoots 1moa.. just not good enough any more for competition -- but still plays havoc on groundhogs. One of my .243's has literally thousands of rounds through it -- and I load it to sensible pressures -- and there has been no sign of group degradation yet.
Jury is still out on my Win 70 .243 WSSM. Haven't shot enough through it yet to see any problems.. but my hunch is that it'll go the same path as my 6mm some day. But I'll have lots of fun with it until that day arrives.
Wish I could drive a car to a million miles on the odometer, too. But that's about as practical a thought as wishing ANY barrel will shoot a million rounds without opening up a bit. Things wear out. So do our rifles. And my body.
