Looks like someone makes/has an odd AK out there.

I picked these up while cleaning up our pistol area last summer and finally got around to sorting out my range brass collection.



The inside of the necks look like the outside- its a chamber issue. The brass is fiocchi, so decent stuff. Looks like something made for fire forming...

I presume it will go back to normal with a FL resize, but with how cheap 7.62x39 is, I don't really bother...

Or maybe there was an "issue" in the firearm's mfg's quality control department ?

Did it shoot? Did it feed from the magazine? Did it blow up? Another quality Kalashnikov

Well, it looks like it went bang at least five times.

wonder if they were blanks of some sort.

The thin part mikes out where it should for neck diameter.

It isn't my gun- I found the brass at our shooting range.

It's in effect a chamber cast. Obviously, they fired off, and I found 5 so it may well have functioned normally.

I thought they did QC steps on these things... never heard of a 2 step neck chambering.

No reports of any injuries at the range this summer, so I dunno, it went bang and left the empties in the dirt...

Saiga AK... l've seen that brass on Warcop Ranges before.

Looks like they opened up the neck portion of the chamber with a 3/8" Craftsman drill bit Helps smooth out feeding, you know.

This is standard on all civilian Ishmash rifles (e.g. Saiga). Supposedly so one can tell whether brass was fired in a civilian or a military rifle.

This feature has no impact whatsoever on the performance of the rifle with factory ammunition. I assume case life for reloading has never been a central criterion in the design of these guns...

Thanks for the info.

Anyone else think the action
opened before the pressure had
let off?

I've found auto brass like that
from various pistols.

On 7.62x39 cases from an AK type rifle, that step definitively comes from a chamber deliberately cut that way. It has nothing to do with the timing of the action.

Russian gun control, and forensic. Probably the only way gun control works, ie., get caught committing a crime with it and....

The sidewall of the case is straight and a false shoulder has been created as if to form to a different chamber. Looks like the sidewall formed but the shoulder didn't push forward.

crbutler . . . . .

It appears those are fired cases. If so, fired cases ALWAYS match the ID of the chamber perfectly. Therefore, I'd say that they were fired in somebody's custom chamber that looks just like those fired cases.

This would require cutting a new chamber (and probably not in an AK-47). The reason for this, is to provide a better bullet alignment for better accuracy. The reamer was probably modified by someone looking for an affordable accuracy gain.

Those cases appear to be perfectly reloadable.

Again, this is not a custom chamber and has nothing to do with accuracy. It is a standard feature on many civilian Russian AK47 or AKM type rifles.

Cases from my own Saiga AKM-type rifle look exactly like that.

7.72X39 fired in a VZ-52?

Saiga chamber eh? Learn something every day.
Only Saiga I ever had was a .308 and that was just briefly. Seems that chamber was "normal."
