The term ‘ring true’ comes from testing of coins back when coins were actually made from precious metals, however it is also a term used in the gunmaking industry and a proven test to see how good or bad a barrel set is. The better the fit of ribs and the join of the solder the better, however not all barrels are equal. A over and under barrel of monobloc construction (or sleeved) will not sound as true as your classic chopperlump or dovetail barrel.
Listen to the three barrels in the audio clip below, the first are a set of barrels that have been destroyed by shooting high performance steel, the second a good set of over and under barrels and the third is one of our own chopperlump barrels. Can you hear the difference?
