My daughter and her friend were shooting my jw-15 and it made a loud bang. It looks like a piece of the end of the chamber is missing, also the extractor came off. I'm starting to think that the Chinese child labourers and political prisoners don't take enough pride in their work.

Notify the ammo company, and keep that piece of brass. They'll want you to send it to them, along with any unfired ammo from that batch that you have. They'll reimburse you for it and then some, and will probably want you to go get your gun fixed and send them the bill. That looks like an overcharged round maybe with too much priming compound. Try it, you never know.

That's dark....:eek:...but shoddy construction of that type is very much inexcusable....:mad:
 
Did it blow out at the extractor groove, in the breech end of the barrel? You said something about part of the chamber being missing...any pics?

x2 Was the bolt fully closed? It's the right extractor, on the ejection port side. Not sure how a round could be discharged on that bolt action withOUT the round being fully chambered and the bolt fully closed. It would seem like a strange place to break were it just a ruptured case. Last time I saw that kind of brass damage was on a re-loaded 12ga. hull that jammed in the chamber. It took allot of force to open the bolt, and the extractor tore the brass under the pressure. (spend shell remained stuck)

Anyhow, thinking (typing) aloud..I don't have an answer. I do own one of these rifles and it's performed flawlessly for me. I'll be watching this thread.
 
The bolt was fully closed,and hard to open. The round had to be pried out with a knife, here is the best picture I can get. It didn't occur to me it could be the ammo, it was bulk winchester.

I would have said the same thing until that happened. My daughters friend ended up with hot gas in the face and ringing ears, I have to say it was the loudest bang I ever heard out of a 22.

I had the same thing happen to me. Powder in the face etc. Mine was a semi-auto though. There's an old thread about it here somewhere.

We determined in my case the bolt had not closed fully due to either dirt or a fault of the shell. A small burr on the chamber could cause the shell to sit very slightly off and allow this to happen. In your pic of the chamber, is that a tiny burr in the 7 o'clock position?

I was using winchester bulk wildcats. Contacted winchester and they take this stuff seriously. They will have you deal with someone in Canada for shipping because of the permits involved.

I got $30 worth of gift certificates and they paid the $26 to replace my bolt (had a tiny piece broken off). They sent me a box with a shipping label so it didn't cost me anything to return the ammo. They also called 6 months later to tell me they were unable to find anything wrong.

There was a recall from Winchester for double charged .22 ammo but it was 2007.
I'm going to guess the round didn't seat properly and popped back toward the bolt because of it.
 
Check the extractor slots where they meet the chamber. If there is missing metal that allows the side of the case to be exposed, that may be the issue. It may be a headspace issue also.
 
Regardless of whether the ammo was defective (double charge or what), a rifle should not kaboom like that. Something wrong with that Norkie rifle's manufacture or design.

I've have a couple of similar incidents but the CZ452 and the other rifle (can't remember which one it was) had relief holes in the receiver that allowed gases from the ruptured case to escape safely without hitting me in the face.

I agree. No .22 should be able to explode like that.
 
I'd call up Olin and see what they say. They're more than likely going to want that casing, and pictures.

Your gun is pretty much a write off now, unless a gunsmith says otherwise. Don't all Norincos now come with a 1 or 5 year warranty? Maybe Olin will help a brother out, it was probably a double charge on the primer that blew the rim off.
 
I'll contact them and let you know what happens. Its hard to see in the picture but there is a small piece of metal missing at the end of the chamber that now exposes the rim of the cartridge. I never looked at it closely before but I'm pretty sure it was there. There are also bits of metal in the action.
 
Before you do ANYTHING else look for a bore obstruction.

I once had an idiot bring in a Remington autoloader .22 with FIVE (yes 5!) bullets stacked in the bore. The dummy just kept shooting, and wondered why nothing was coming out of the spout....and why all the crap was coming back in his face.

My first thought was a bore obstruction, but there was nothing.
