    Trivia Question for Shooters

    Read this one and thought there may be some interest out there:
    In terms of shooting time elapsed, what is the average lifetime of a rifle barrel?
    To perhaps make it easier I have included the poll to help you think.

    Political correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

    How long is the barrel? (Although I'm often told that it's the width, not the length of the barrel that's important!!!!)

    For all the questions: it doesn't matter, the poll options are great enough to allow for variables.

    Are you including sporting/recreational AND millitary ?

    I've chosen 18 minutes purely because I can't see our armed forces changing barrels every 18 seconds...

    Chuck Norris has the greatest Poker-Face of all time. He won the 1983 World Series of Poker, despite holding only a Joker, a Get out of Jail Free Monopoly card, a 2 of clubs, 7 of spades and a green #4 card from the game Uno.

    Muzzle velocity of a bullet is (roughly) up to about 1500 metres a second. Give it starts at 0, we'll assume an average barrel velocity of 750 metres / second

    A bit short perhaps, but lets say the rifle barrel is 50cm long.

    So, each bullet spends 0.5/750 seconds traversing the barrel = 1/1500th of a second.

    18 seconds of barrel life will give you 1500*18 shots = 27,000 rounds fired
    18 minutes = 1,620,000 rounds fired
    18 hours = 97,200,000 rounds fired
    18 days = 41,990,400,000 rounds fired

    A 1.0 metre barrel would halve those figues, 18 seconds is looking good to me...

    Or WTF option. I hope burgs has tested this on his property, so we have accurate figures to rely on, but coaches analysis seemed good enough for me, 18 seconds for me
