    What a great, useful thread. Maybe take 5minutes more next time and try to come up with a real question.

    About 3 seconds of barrel life.

    Dave, this is a very knowledgeable group of folks, myself not included, and they could probably give you a general estimate if you were MUCH more specific. But like many groups of intelligent people they have a low tolerance for foolishness.
    Try listing things such as caliber and bullet weight, barrel matterial, contour and use. Rapid fire? Meticoulous cleaning or none?....

    I was being serious, maybe a little over generous with the time for a real hot round.
    But a 220 swift or .243 with 55 grainers will have around a 1 second barrel life. I was
    just letting him do the math. 24 inch barrel 2ft/4000fps=.0005 seconds for each round
    in the barrel. .0005x2000=1 second . 2000 Being the rounds fired. That also is being
    generous for those rounds. 3 Seconds is the generalized .308 barrel life with 2700fps
    and 4000 rounds.

    Loner I am impressed. I took that wrong. You actually produced a formula for the amount of time a barrel spends with bullets travelling in it. And it sounds rather accurate.
