    If I agreed with you, we'd both be wrong.

    The last thing I want to do is hurt you,
    but it's still on my list.

    That doesn't really show anything though, asides from the filthy 14 that lasted a gazillion rounds. Not a comparison, and doesn't prove anything, other than a BCM standard barrel lasting a long arse time.
    From TOS ... "buy the shit out of that thing, all the mil spec is just nonsense."

    Maybe as close as the OP gets.

    Yup. If I recall, wasn't DD going to do a big ordeal about their HF barrels? Still would have been nice if they purchased a few competitors and did a test along side of them. (this test was mentioned on T.TV).

    The problem is that throat erosion is going to be dependent upon both how many rounds are fired and how rapidly those rounds are fired. There is not a definitive number because the manner in which the rounds are fired is a critical component of barrel life. You can make a lower quality barrel last longer and tear up a higher quality barrel faster by simply firing less rounds per minute or more.

    Barrels are an expendable component. You will spend many multiples the cost of the barrel by buying ammo before you've "shot out" a barrel from any respected manufacturer. Is there a particular reason you're concerned, or is this simply a question for the sake of learning the science of barrels?

    The question could be will you ever see the difference in how and what the barrels are made of. I would look in to the quality. Stainless is softer. A high quality of either will be better than a low quality of either. As mentioned the filthy 14 how much better do you need than that. Maybe if you get into full auto and burn through thousands and thousands of rounds you could see a difference. Quality always wins over razzel dazzel.

    Well the Bushies and the spikes Andrew ran in the lucky gunner labs test were shot out by 6-10k rounds and all were CHF.

    I would say 6-10k of extensive fire is what you can expect from a Colt or BCM barrel as well.

    Yes but as was said above, the rate of fire is going to have a massive effect on barrel life. In the lucky gunner test they talk about the rifles getting so hot they couldn't hold them, the average person is not going to burn through 10k rounds that fast.

    Heating the barrel steel up to the point of elasticity and then continuing to pour bullets through it is going to tear up any barrel and I don't think the lucky gunner test can really be used as a measure of barrel life, except under rapid fire conditions.

    No doubt, my point was that I would expect the same amount of life from a button rifled Colt barrel as I would a FN CHF barrel if both were fired like Andrew and his people did.

    Since when has Bushmaster CHF?
