As I recall Nash Buckingham's Fox HE Bo Whoop achieved its nickname from the way it sounded across a Duck Marsh.
Several of my early Lefevers are overbored more like a gauge than by .005". That is a 12 is bored to approximately 11 gauge or around .750". I suspect it was intended for use with brass shells, thus oversized wads. do not know that of itself would cause a change in the sound.
Jim Kelly, Darlington, SC gunsmith who restocked Bo Whoop, and actually made the world aware of it's existence, took Bo Whoop to a river swamp with some duck loads and had an associate fire it while he waited several hundred yards away and listened. He told me he could discern no unusual tone to the report of the gun.
Maybe it had something to do with the lay of the land (water), possibly it was a particular duck load of the day, ..........or maybe it was a fanciful tale made up by Col. H. P. Sheldon.
