Most likely a double load of fast powder by a handloader. There are many newbies that don't use caution( and even do it on purpose) and load the wrong powder, or use way too much thinking how "cool" it would be to make their gun a "super" gun. Most pistol brass is good for 20k cup or below and rifles are good for 30-50k cup. Why not load pistol brass up to 50K cup? Hold muh beer and watch this!
Probably compressed load of either Bullseye or Unique. 1st detonated 2nd & 3rd flash detonated. Had a similar experience with a Smith Model 10 in 1977. Novice reloader compressed Bullseye & with the exact results.
I do cowboy action shooting and saw a similar picture in the SASS (single action shooting society) publication"the cowboy chronicle". The cause was a unusual but reproduceable error with a progressive reloading machine. lead bullets are lubed with a waxy coating and a buildup of lube can cause a bullet to stick in the seating die. then the next case and bullet are cycled thru giving a case with two (2) bullets on top of a very compressed powder charge. The guy who had the blowup was unhurt and by weighing the entire run of reloaded ammo one at a time found 3 or 4 others that had the same problem. the solution was to keep the seater die cleaned out of lube buildup and look for any cases in the output that didnt have a bullet seated.
I know these are old post but I wanted to add to this, I had almost the exact thing happen to me saturday. I had reblued a argentinian .38 special and after i finished and it dried I fired a round, the bullett actually ejected from the casing but at the same time the casing, cylinder and the top of the gun, just like in the picture above, exploded, thank God it didnt hurt me and no one was around but me, but I have teenage cousins that shoot with us a lot and I can only imagine the damage that could have been done. Anyone know why this happens or what could have caused it?? Thanks for listening.

Geez. My dad had a S&W sheer off a bullet and shoot him in the arm, but this takes the cake. I hope the dude who pulled that trigger still has a hand.
New digs, btw. Stop by and check them out: http://feedyouradhd.com.
Wouldn't this be caused by a catridge with much more powder than it should have? (I'm a novice, and just guessing...)
Lesson learned for today: Give up hunting wabbits.

Was the previous round a squib? That could cause the chamber pressure necessary to explode the cylinder.
