Here was me thinking all the doom and gloom South Sayers had given up on this subject. They seem to have stopped on this side of the pond after a large number of gun users sort of fought back in the 60s & 70s. This dangerous chant was uses by large numbers of gun retailers to aid in the sales of cheap Spanish guns and at the time a lot of very serviceable top maker Damascus barreled guns where scraped. In the end the proof houses said that if a Damascus barreled gun was in sound usable condition and IN PROOF it was safe to use Cartridges of the correct chamber length and shot load. Unfortunately you folks do not have that luxury, so this scare story will be hauled out and polished up with regular monotony to see who will believe it.
