Bad Day At The Range For Someone

[tndrfttom]

Someone left a bunch of once-fired and reloaded brass on the floor at the range so I swept some up and brought it home. As I was sorting out the obviously-reloaded brass from the stuff that looked like once-fired commercial I ran across these two blown-out cartridge cases. I have no way of knowing what they were fired in but it appears to be two different pistols based on the shape of the case failure and the primer indent. One case is marked WCC 1987, the other was WCC 87 (with NATO mark).

There were less than 100 of these WCC 1987 and WCC 87 cases in the stuff I picked up and none of those other cases displayed signs of swelling at the web of the case; But to be on the safe side they went into the brass recycle bucket.

Ouch! Bad day, indeed.

I meant to sweep those up.

Man that almost looks like some bonehead chambered the wrong ammo in the wrong gun. Both blown out just above the case head ? Somebody smarter than me will come in and sort this out cause I'd be really curious

The rounds pictured look like they were shot out of an unsupported chamber. After a few reloads, the brass weakens and the web blows out. When the web opens up like a can opener, it is usually a case that has reached the end of its useful life. I have also seen this happen where the head completely separates from the case. This is called insipiant case head separation. You also see this a lot when guys shoot .9mm Major and then someone tries to reload the case. At some point, all brass will reach the end of its life. It is very difficult to see this with the naked eye. Do not assume that it was a double charge.

That's what I thought when looking at it. In my noob days I did something similar with same results

 

[kimporter]

thats looks like what they call a "Glock bulge",but the firing pin indent is not right.early glocks did not have enough support under the casehead because of the feedramp and they did that,

I am with you on this one. That was my first thought. I believe you are right on the money.

Witnessed this on a public range years ago with once-fired brass used in a TEC-9 or KG-99, don't remember which. The owner had just purchased it at a local gun show and was shooting it for the first time.

The gun was a blow-back action and clearly the brass was in the process of being extracted from the chamber while there was still pressure in the bore. Nothing ruptured, but lots of bulges.

Or just overloaded ammo, like 9mm major??

+1 with post 5 & 8

Too much metal removed from the ramp/rear of barrel area.....

or too hot a load for the metal that is in that area if the owner
was shooting "Major Loads" in the weapon.

I does not always have to be from a Glock..............

Time to back off a touch if reloading that ammo, if you want to try to load it more than one time !!

Could these have been fired in a .380? If one were to chamber a 9x19 round in a .380 pistol and fire it slightly out of battery, this is exactly what I would expect to see.

The case on the right has an impression in the primer that is typical to Glock pistols. Since somewhat less than normal support is a design feature of many early Glocks I would have to guess that both cases were fired from a Glock.

Looks like a "Major 9" to me, maybe just a little too "Major" in an unsupported chamber.

Glocks had that problem in 40s&w not 9mm

 

[rwsmith]

The three bears....

Unsupported chamber
probably weakened cases
hot loading

If they don't tradethe gun, it would be a good idea not to load those cases so hot.

Happening once would be disconcerting. Twice.....

Packing that Titegroup in there, ain't cha?

Neither of those cases were from a Glock, which use a flat-sidedstriker, not a round one. That old story goes on and on.

Not unless the striker had been modified to be round??
