Barrel "Ringing"

"Ringing" the barrels of a multi-barreled gun to check the integrity of the rib joints seems like it should be an easily done and easily understood procedure.  Apparently, it's not.  It seems that some can't tell a "ring" from a "clank".  I don't think that this is because of any hearing deficiency but rather, they just don't know exactly what it is that they should be listening for.  The following videos will hopefully shed some light (or add some volume) on the subject.  Another thing to keep in mind is that the "ring test" is only valid when the barrels are bare, no extractors, ejectors, forend latch parts, cocking slides, etc.  BARE barrels.  This applies especially in the case of American guns because of the level of imprecision with which these parts are fitted.  If these parts are left in place, they will affect the way the tubes vibrate and therefore, the way that they sound when struck.  The barrels must also be hanging freely, ideally from a wire by the hook.  Definitely not with the lump pinched between the thumb and forefinger, or with the hand wrapped around the chambers.  Finally, it does not matter whether the barrels are for a rifle or a gun, they should sound the same.

You'll want to make sure that the volume is turned up.

Here is an example of what you don't want to hear.

 This is the sound you do want to hear.   Not "sort of" or "kind of" or even "pretty close", this is the only sound that will emanate from barrels with sound (pun intended) rib joints.

 For comparison, here is a video with both barrels, hung side-by-side (ha! I kill me).
