Has any forum member ever seen a Single Action Revolver blown up where the cylinder wasn't the first thing to give way? ***** ..... not seen by, but described to this shooter by silhouetter Eric King, his Seville .375 Super Mag breaking horizontal along base pin. While shooting rams @ 500 meters. Cylinder held, frame let go. Call it a broken, as opposed to blown-up, revolver. Haven’t heard of, or seen, a Ruger, Smith & Wesson, or Colt frame break from fatigue. As cylinder contains cartridge, a blow-up starts here. Short of surrounding it with dynamite, don’t know how a revolver could implode. David Bradshaw David, I agree. Of course, my point was if a top strap got blown off and in the end the gun was destroyed, you could easily extrapolate that the cylinder gave way first. I can see a frame breaking from a weak spot or casting flaw. Maybe by other things such as loss of tempering from drilling, etc. But, I'm with you, I've never seen one blown up (from ammo) without the cylinder giving up. Thanks for posting this information...

The gun smith shop I spent my spare time in had a 1917 S&W hanging in it with a split barrel and 6 countable hardball bullets in it nose to tail, cylinder was fine. It did tweak the frame a bit. This was just operator error though and not a blow up. Guy brought a mod. 29 S&W in one afternoon while I was there, wanting the gun smith to send it back to Smith & Wesson for repair. Everything from the base pin up gone and side plate bulged badly. His story was he wanted to load some ammo for the 44 and didn't have any data but his .357 took 1 dipper of powder so the 44 should take two. The gun smith sent him, On down the road!

Not a single action and not really a "blow up". Smith & Wesson replaced with new revolver. Over torquing when barrel was installed was reason given for failure. Found the barrel/shroud assembly on the top of the pistol house behind me. About 900 rnds thru revolver when failure occurred.

Good chance a split or broken cylinder scars the topstrap----evidence of high speed hammer-blow to bend or break topstrap. There is no reason for the topstrap to rupture upwards by itself. David Bradshaw

Peening swells end of center pin, eventually causing pin to stick in hollow extractor rod. David Bradshaw

There is no reason for the topstrap to rupture upwards by itself. David Bradshaw I had opportunity to inspect a FA83 454 Casull once that had five "hammered" lines running lengthwise on the cylinder. One over each chamber. The owner was loading the Casull so hot, the cylinder was expanding and hitting the top strap. A testament to the strength and ductility of 17-4 Stainless.

Well, not exactly a blown up revolver,, but a couple of things I've personally seen.
(1) My first Redhawk Ruger. It had the barrel separate from the frame. The gun had only been shot with mild to mid-range loads. Fired it once,, and the barrel & scope "flew forward" and I was left holding the frame & cylinder. It took Ruger several years to determine that the lube used on the barrel threads,, when left to dry, had changed viscosity enough to cause an over-torque situation. Ruger replaced my Redhawk.
(2) A S&W .38 spl pocket DA revolver. Can't remember the model. Apparently a shooter loaded some very, very hot .38 spl cases with serious magnum loads. 5 shots,, and then the gun wouldn't open. The frame stretched to where it showed visible compression of the metal where the side plate & main frame met. At one corner,, at least 1/16" gap. The cylinder,,, only able to extract (1) piece of complete brass,, and the others the case heads popped off,, leaving brass welded to the interior cylinder walls. The gun held,, but was ruined.

Closest to a blow up that left the cylinder undamaged but cracked and twisted the brass frame was when one of my cousins had a Remington clone cap-and-ball chain fire.
