The article about the full-auto single action revolver is in the August '09 issue of "Handloader". It was a Colt Single Action Army, made in 1937, chambered in .357 Magnum.

I saw a Ruger Blackhawk 44 Mag that looked like this except the frame was broken in two!
The problem with this blow-up wasn't an overload. It was caused by the bullet crimps failing and the bullets moving too deep in the case, which caused the pressure to sky-rocket.

Grizz, don't understand, weak crimp will cause bullets to move forward, out of the case during recoil, not back to form a compressed load. cylinder lock will be the result.BTDT

Usually bullet setback is caused by the bullet hitting the feedramp or the front of the magazine, in autoloaders, under recoil but with revolvers the cartridges tend to grow under recoil.

I do understand I've only been reloading and shooting hanguns since 1964!
I saw the gun at a local gunsmith's shop and, also, questioned their explaination. They had found that all the other cartridges had the bullets setting deep on the powder. The shooter was an experience shooter and reloader and hadn't loaded them that way?

Not to start a fight but... I can't see any way recoil in a revolver can force a bullet INTO a case... The gun moves backwards and the bullets want to stay in place.

1- That didn't happen from recoil.
2- So were all the other owners of KB's I've seen. Every single one.
Just my .02.

Regarding #2 in Stovepipe's post:
Last night I was looking for some info on a S&W I have and found a forum discussing it. Someone on the site was talking about the load he had developed for this airweight revolver. It was around 5% over the max powder charge in the manual. Later in the thread he was complaining about the quality of the gun because it was showing some damage from shooting his loads...
By the way, I know from personal experience that folks who have been loading for a long time (like 30+ years) STILL make mistakes. Luckily none of mine ever blew up!

Your sure they all went off or when the one ruptured the cylinder it still was hot enough to ignite the 2 charges?

I stopped and talked with the gunsmith who had the 44 Ruger that was blown up. He said that he feels that that gun was dropped. It was loaded with soft lead bullets, which may have been slightly undersize, and the crimps had not retained the bullets when the gun was dropped. He also mentioned that most factory ammo has a secondary crimp below the bullet to prevent the bullet from moving farther into the case.

Squib followed by a normal load?
That would put a bullet in the barrel followed by another with no place to go.
