How do you measure barrel length?

    I shoot competitive and it comes up as a definition of divisions.
    How do you do it?

    Drop a dowel (pencil) down the barrel to the breach face - so you get the barrel and the chamber?

    Is it different for wheel guns ?

    TIA

    Wheel guns, the cylinder (chamber) is not measured, so it would be forcing cone to muzzle. Any other firearm the breech (rear end of barrel) to muzzle (front of barrel) is barrel length.

    An odd thing.. the .357 mag came to be in 1935 and only was available in revolvers for quite a darn while.
    The thing is, the published ballistics for decades for that cartridge came out of a quite long unvented barrel.. I forget.. 9-12"? when in reality they should have probably used a 6" vented all along to split the difference between the 8 3/8 and 4". The 4" was the most common carried length for lawmen for many years.

    Their front page says, "This site is down for maintenance. Please check back again soon." Sounds like they're working on it.

    Ruler works in a pinch on pistols. Yard stick for rifles.
