If I had to guess, I'd say squib followed by full power round, but you'd normally see a bulged barrel, unless the first bullet stopped right after the forcing cone.
Hey Tfogger. That was my first thought as well (squib load and followup shot) that I posted earlier in the thread. I don't think that would be likely anymore because much of the pressure would have been released between the cylinder and forcing cone.
Just theoretical, but I don't think there would be enough pressure left over to detonate the walls of the cylinder. Seems that the gap would allow pressure escape in front of the projectile as the round exits the cylinder and once past that point, the excess pressure still being exerted behind the projectile would escape the same way.
