A friend emailed me these pictures with a long drawn out story about squib loads. I won't bore you with that because I can't verify the story but the photos are facinating. It's amazing that much pressure can be put into the barrel without bursting it. I count 12 bullets in the barrel and based on the shape of the last bullet it looks like a round was fired after the barrel was filled up.
Maybe someone else has seen these and knows the whole story.
