The theory of a un-ignited slow burning powder being pushed down the bore by the portion that was ignited by the primer and then spreading out in the bore and igniting across more surface area; an event labeled "detonation", has been around in the rifle ballistician's vocabulary for decades. There's actually some test data to confirm support this in rifles. Is is possible in shotguns? I dunno.
