What Would Cause This? (AR 15 Issue)

[Batteriesnare]

If it is factory ammo like the guy claimed then I would call winchester with the lot number and also do a quick google search to see if anyone has had problems with that particular lot. If so that would make a good case against winchester to get them to send you some new ammo.

Excellent sounds like a good plan, thank you!

Quick addition. Went back to the range after noticing I had two different lots. The WB30 is stamped 04, where as I received a few boxes of SC61, stamped 01. It was the SC61 that screwed up (bad powder was what I found online) the WB30 ran today without issue. Is it worth contacting Winchester over the 4 boxes I have left?

Bit off topic and I am not sure what "your" range is, but..
Batteriesnare: was taht you I saw up there yesterday (Tuesday)?

I was driving a lifted, white with peeling paint, old beat up GMC pick up. I got out an asked what you were shooting as I saw the AR being loadded into a Jeep. This was about 13:15.

Heh, small shooting world if it was you.

yeah I would call them and make them send me 4 new boxes of ammo. that is $40 of ammo give or take. They need to make it right.

I don't recall your vehicle, I don't have a jeep though, and I was wearing my plate carrying vest and had a bunch of steel set up. If it was, hello to you as well!

Nope, I don't think it was you then. I fugured it might have been, or at least another user here.

Sorry to bug ya.

You're darned right it's worth it - on many levels. First off, you have to recoup your investment. I'm guessing that you purchased the ammo with hte intent to use it and with defective ammo, you can't use it. Secondly, you could have been injured and may have damaged your firearms because of their ammo - don't let it cost you any more than it already has. Lastly, you have to hold them accountable for their producing something that is sub-standard.

Thank you for the offer, I may have to take you up on that. I'm a little cautious to call Stag out on that, because all of their rifles are 5.56 chambered, and all are supposedly mil spec. Would you consider a Stag factory rifle to be "hobbist level"? (Just curious, you won't hurt my feelings)

Thanks!

There's another possibility. Too many barrels are actually .223 chambers, despite what the barrel may be marked. DPMS is notorious for this issue. As are other hobbist level weapons. Anyhow, this can lead to pressure spikes that pop primers.

I have one of Ned's reamers, plus a plethora of AR tools. If you want the rifle looked over, let me know.

I have a Stag model 2 and have not hand any issues with shooting centurion, priv, silver bear, ultramax in 223 or 556. I vote this is an ammo issue not the rifle, you tested 2 other ammos and no issue, I say its the batch not the rifle at this point. See if Winchester will refund or replace the bad ammo.

Sorry to hear about your troubles, Chris.
I am "the guy" who sold the ammo. It was bougth from Jensen's a few years back and kept in an ammo can with a couple of large dessicant packs from the time I got it.
I did not handle the ammo in between and never noticed the two different lots.
You could contact Winchester and see what they have to say.
