Blown cartridge in my CZ

Couple of days ago I went to my range to do some target practicing with my CZ SP01 Shadow.
At some point during shooting a louder and smokier than normal shot interrupted my practice.
Upon initial inspection I found spent cartridge with a blown cup still in the chamber. I pulled the cartridge, field stripped the gun, checked for any visible damages and gave it a quick cleaning.
I then loaded and shot one cartridge and it wasn’t extracted nor ejected after the shot.
Upon inspecting extractor I discovered it was broken. What I’m trying to figure out is which event happened first and caused another – blown cup broke the extractor or the other way around or is there anything else I’m missing?

P.S.
I forgot to mention I was shooting factory reloads and so far I put about 400 of them through my gun without any kind of problems.

Extractor is always very likely to get damaged in a situation like this. That round looks like it was massively overloaded. I doubt it was an out of battery issue as even the base is heavily compromised.
 
Yeah look at the head stamp. It's almost ironed right out.

If all that broke is your extractor, I'd say buy a lottery ticket.
 
The extractor looks like a mim casting, so a bit more brittle than a forged steel one.

The cause might also have been a telescoped bullet.
If the bullet slides .010" back into the case, pressure doubles.
Since 9mm and .40 cal. have SAAMI pressures approaching 35,000 PSI, a blowout isn't surprising.
.44 magnum has a SAAMI maximum of 36,000 PSI, just for reference.

Can you provide a little more reference for the bolder part? 10 thou from where? Certainly seating an oal with .010 difference isn't going to double pressure...
 
I had this happen to me a long time ago. It was a double charge on a 9mm 124 grain bullet. Factory ammo and factory reloaded is quite different, what brand was this? Mine was with Western Munitions, funny enough same 250 round box also contained 3 squibs. Needless to say, no more western munitions for me.
 
Glad to hear you're Ok. As others have mentioned it looks like it was a very HOT load. I'd inspect your gun very carefully for cracks or any other possible damage. The CZ is a stout gun, probably very fortunate to be shooting it rather than a Glock lol

The ammo was Identical to what you described.

Wow, not good for Western's reputation.

I've shot over 6K of BDX ammo without a single issue, so "re-manufactured" ammo can be very safe when produced properly.

Give Western a shout, I'm sure they'll want to investigate.

What clues would be pointing to out of battery fire? I'm not sure but my feeling was that the slide did not lock in completely when the shot was fired. Maybe because i felt hot gases hitting my hand and face and also black carbon stains on my hand. From what I've heard that's how out of battery fire behaves. So when i found out the extractor was broken, i thought maybe a piece of it prevented slide from locking completely causing out of battery.
 
I reload all pistol rounds... I always lean towards powders that will spill over in a double-charge situation for this very reason.

Glad you just experienced a broken extractor.

I only trust myself for reloads as well :) Hope it all works out.
 
Not good whatever the brand of pistol is, but checking for additional damage is a good idea. As for reloads, I make my own and I look in every case before the bullet goes in. I have gone away from .38 special as I can't see in the case as well as 9mm or .40 which are my 2 main reloading cartridges.
 
Ouch! I just bought a bunch of Western .45acp.. I've shot 1,000's of rounds of Wolf,Centaure and Wasp reloads in a variety of calibers without ever having a single issue. This is my first buy from Western and now I'm a little hesitant to use the ammo. :(
 
contact western reloads. Were it me in Customer service I'd ask for the gun and spent casing and be sending you a new pistol.

Not sure I'd shoot that gun another time, Your life is not worth it. You don't know what else has been compromised. Your fingers are not worth losing over saving a buck or two.
