    Dunno, but the short barrel configuration for the Anschutz match rifles have barrel lengths of 19.6" for .22lr, and they're accurate to olympic standards.

    I think it was either 16 or 19 inches as I recall. 19.6 does a nice job on some of the short barrelled Anschutz models anyway.

    I have the article somewhere, but that would involve digging through stuff to find it, so I'll just defer. Funny how little barrel is really necessary though.

    found this link which substantiates my earlier post, its between 14-16, the
    determining factor would I imagine be the burn rate of the powder in the bullet being used, on the same topic, guns and ammo magazine ran a test way back to see how long could you make the barrel of a rifle where it would get to the point that the bullet would decelerate in the barrel to the point of falling out the muzzle onto the floor with zero energy..anyone guess that length?
