I bought a new case of wolf gold and noticed little changes on the box from previous lots I have purchased. Anyways I shot about 60 rounds today of this new lot and noticed 2 split case necks. Is this common? I can't remember the last 1000 round case doing this at all. I have also had about 4 or so split necks from federal xm193 out of around 200 rounds as well. Could it be the rifle or just a bad  anealing job?
Rifle I shot them in is s complete BCM upper and spikes lower. The rifle ejected everything at about 2 o'clock with a H buffer.

First time hearing about this, also with Federal.... I would say probably the barrel/chamber issue?

What would cause this? The rifle has fired over 500 rounds and everything shot and ejected fine. Should I contact BCM? I don't think head space would cause a neck issue.

I rarely hear people talk about split neck in AR so I am not too sure about this.
But since both the Federal and Wolf Gold got split neck, I have a feeling it might be the gun.
Perhaps try another brand in the same 5.56 spec ammo, see if there's any more problem.

If the problem continues, that means that you probably have an imperfection in the neck of your chamber.
Try cleaning the shit out of the chamber, and try again... if all else fails, call BCM

Ya I can try that. It functions perfect and the rounds group well. Is it bad other then having to throw away some brass?

You will have to hear from other guys if you want to know if this is 'bad', but for certain this is not normal.
You should just do a google search and form your own conclusion... probably faster and more overall informative that way.

From my own personal experience, I've only seen split necks in my friend's surplus CZ-52 pistol which shoots the 7.62x25 Tokarev ammo.
We notice the split case when he was shooting the well known crappy Bulgarian surplus ammo, although it functioned fine.
With other quality surplus ammo or modern production ammo the gun functioned perfectly fine, and with no split necks.

I tired that before I made this thread. Basicly what I found online is if it's happening every once in awhile it's a bad piece of brass. So that's why I posted this thread in ammunition

Hmmmm, sounds like the chamber might be a bit too big around the neck to properly support the neck, therefore more stretching of the neck when fired.

I could be on an army range picking up brass, all day long, and never see that.

I've also retrieved and tumbled a ton of Fed and Wolf Gold brass and never seen that.

The gun would be the biggest suspect.

Even though it's on like 1 out of 50 rounds? It's a factory BCM upper and barrel

Like I said before, best thing is to try another brand of ammo and see.
I, too, think it might be the barrel since you've already tried two different quality brand ammo with the same issue.
1 in 50 is still alot if you think about it.... 2% failure rate is not acceptable at all to any ammo brand.
I've shot 13k in one of my rifle, and close to 12k in another, steel and brass case ammo, never seen a split neck before. (I pick up my case for my friend who reload)
It doesn't matter what brand of barrel/upper, there will be lemons...google any brand, and perhaps deep research, they are not always perfect all the time.

Try keep shooting it and try another brand of ammo.
Split neck cases is not a good thing, but it might be okay for you to keep shooting since I don't think it will harm the rifle.

Correction:   My rifles had 12k & 13k through it with no problem with any kind of ammo, not 1.2k & 1.3k

I've shot 2000 + rounds of Wolf Gold in 3 gun matches over the last 2 years, 15-20 club matches. I have not had a single failure. I pick up as much brass as I can. I have not seen a single cracked neck.

Well I ordered the exact upper again so I can get one quick and then send this one in. I want to use it for a class this weekend.
Hopefully the new one will be built better.

Haven't shot much, and none recently. But I seem to recall the jacket of their bullets is a bit thick.

That is actually not true.
See this thread about the jacket thickness.
The wolf gold bullet is actually the thinnest of the 3, thinner than IMI and Federal.

The reason it looks 'thicker' is because the boat tail is rolled at the end.
