[QUOTE="Greyfox, post: 1232091, member: 10291"] I think that claims of barrel life, especially those claiming such high numbers as 4000 rounds need to be qualified. I have shot out a few. 308's that I used for competition. This round is generally claimed to to have a very long barrel life with claims in the several thousands. Mine were used for competition and routinely shot to the point when the barrel would be hot after 20 round strings in the summer heat. I would see .5MOA deterioration of group size between 2000 and 2400 rounds. Perhaps, not running so hot, or, a 1 MOA standard would give longer barrel life.The standards for defining barrel life really needs to be understood to have much relevance for a given use. My 6.5x284'used for long range hunting and stone busting is still holding .25MOA after 6 years and 700 rounds. I expect to see 10-15 years of life for how I use it. Bench rest shooters may replace a barrel halfway through a season, thus its reputation as a barrel burner. It's barrel life likely no different from a 270 or 7Mag, were they used under the same conditions. .IMO. [/QUOTE]
