My Norc jw105 experience...

I have had jw-105 for about a year and a half now and i haven't had any issues like that, yikes! Glad you're ok.
On mine the trigger was too long for the trigger guard, so it rubbed and stuck on the inside of the guard. I was able to shim the guard out with a few washers and files a bit off the bottom end of the trigger and it's worked fine ever since.
 
The ammo that you have left from that box, did it shoot fine in other guns? or do you still have it?
I got a few boxes of the 40rd pack of wwb. I have no idea if this was a new box, or the combination of a couple old boxes(same load, different lots) put together to save space.

heres some more bad.
just about bought one a while back..not any more.

Ok, I had a look at the 3rnds that I extracted. Hard extraction like this guy describes, and I didn't notice before, but the cases seem to be the same as well:
"note the area where the neck meets the shoulder. When laying the brass onto a flat surface and rolling slowley, you can see a wobble as the neck rotates in relation to the tables "
 
is that clear tape on stock? used to hold the magazine in maybe?
Just had it there to hold the bottom metal in place after remove the 2 action screws.
Never bothered to remove the tape.

Re: Barrel obstruction. The was none, I ran a patch down it last night, checked it again before shooting.
After I finally got the bolt open, the case head is stuck to the bolt, the case body is stuck in the chamber, the primer was sitting in the barrel(eventually fell out as well).
And the bullet was high on the target.
There was a metal part in the action, that came lose and fell out when I got the bolt open. The metal part ran the length of action, and looks like it had the feed lips on it. Odd part.
 
Take a pic of the chamber...I want to see how it looks.

Might as well ask me to take a picture of a footprint on the moon!
Best I can do:

All I got to work with is a camera phone, a dark house and a flash light.
Looks like a chamber that has a case stuck in it. Case looks like it came from factory stuck in the chamber.
 
The single most common cause of rifle kabooms I have seen is pistol powder in the case. This has happened with factory ammo, too.

After the fact this is hard to detect. because of the way an ammo production line works, there may only be one bad round in your 100 rounds of ammo. BUT, Winchester will know about it because they will start to get reports of blown up rifles with Lot # XYZ.

A rifle defect can be found, because you have the evidence. The best place to start is the fired cases. They are now images of the chamber, and measurements can be made. Do you have a case gauge for measuring headspace? IF not, mail me a case and I will measure it for you. I doubt that is the issue.

I have seen a case burst down through the magazine like that, because of excess headspace, but your rifle blew up. That looks like an over pressure event or a metal failure event. Maybe bad heat treatment.
