I've got a friend that toasted one a just over 700 rounds and another fella's rifle gave up at about 900. I don't remember the brand of barrels, but I do know they were of quality. To short a barrel life for me... My 6CM has 5 inch less winddrift at 1000 yards over the 6.5x.284 and will yield 4000 + rounds of accuracy before it starts giving up.
