And...........
The last trip I made to my gunsmith's shop I saw a Smith & Wesson barrel, apparently from a Model 10, blown out from a squib load. The bullet appeared to have been stuck about 1/2" behind the muzzle. There was a large rupture running back from the base of the bullet about 1 1/2"~2" toward the frame. The bullets were JHPs. My guess is that maybe the first cartridge got skipped in charging, and the following got a double charge.
My gunsmith, Keith Warner, and I, both marvelled that that much pressure built up in the barrel, which at that time was a tube open at one end. Would have thought that would have allowed the pressure to dissapate somewhat.
