The ignition of the expelling charge placed in a squat shell ejected 7 helical rounds with an extremely high rate of fire of several thousand rounds per minute.The gases formed after the ignition of the propellant does not only eject the first projectile but also force the centered positioning of the arranged in a spiral and successively pushed them out at minimal interval.

Consider my wits boggled...
Sorta half-sib to Napoleonic-era naval 'volley gun' ??
Certainly seems a tab more practical than 'stacking' rounds' system...
Um, at the larger end, would it provide a 'salvo mortar' system for launching a bunch of top-kill hurt in 'shoot-n-scoot' mode ? Seems to side-step usual issues with getting later rounds away...
