Stan, I"ve shot a fair bit of primer wads in BPCR/TR competition loads. I find it amazing at what merer rifle primers can burn through. Shot shell primers could do much more I suspect. However, I don't think that's required here. Just moving the powder-filled wad down the barrel a bit until enough powder gets past the wad or primer fire going the other direction and then ignition occurs and the gun fires leaving the wad (mostly) in the barrel and scorched on both sides.

But who knows for sure? In any event, a significant disaster was avoided because of a sharp onlooker. That's all that matters.
