*** Advisory Warning - June 8, 2017 ***
WOLF Performance Ammunition has received notifications relating to Smith & Wesson M&P-15 rifles that are discharging out of battery which is evidenced by a lack of damage to the chamber and barrel extension. This shows that the rifle’s bolt did not lock into the barrel, yet the hammer was still able to strike the firing pin to detonate the cartridge and cause a failure.

Advisory - Wolf Performance Ammunition, steel cased ammo, brass ammo,

This sounds more like a weapon problem than an ammo problem.
I'm not sure I understand.

I was thinking the same thing but Wolf is the one posting this to seem to say it's the ammo?!?! Or maybe they're just trying not to blame anyone for fear of loosing customers?!

Another thing is they didn't mention which ammo. They say M&P 15 which is 223/556 but they SELL (Wolf is an American company and doesn't make ammo) quite a few different types from different plants and countries around the world. Steel case comes from Russian plants (Tula) but brass comes from Taiwan (used to be PPU many years ago).

Wolf gold has been the go to for inexpensive yet well made range and practice ammo. Prior to the election they were selling around $300 - $320/1000rds. Now they're $270 or so.

I have around 350 rounds of Tulammo which I was told was made with the Wolf, I wonder if I should take caution when shooting those.

The other way around. Tula makes ammo for Wolf and sells under it's own name too.

Wolf ammo is a trademark of Sporting Supplies International out of California

Thanks, guess I will shot a few and see how they act, but then it only takes one to mess up your day.

The warning was June 8th. I think if there was some serious problems the internet would be blowing up with all kinds of posts about damaged rifles

Keep your chamber clean for sure. I have shot a bit of Wolf and Tula in my early Sport with no trouble to report. However in a Savage .223, after just a few rounds, cases were very difficult to extract from its tighter chamber. Since then , I have been reluctant to shoot the balance of my Wolf 62gr ammo. If and when I do I will devote extra attention to the chamber cleaning.

I have been shooting WOLF steel case ammo since December '06 in my Sport I. And, in my AR-556 since early '16. I have not had ANY problems with it. I have close to 2K rounds of it and will keep shooting it as normal. :)
 
Talked to James at Wolf CS.

James says it's specific to the M&P 15. He said with all .223 Wolf sells they will usually get a couple reports total per year regarding out of battery discharge for all brands of rifles. But this year they have had seven out of battery reports with the M&P 15. James said it includes both steel and brass cased ammo. So... with the unusually high OOB reports they posted the advisory warning.

Which begs the question, have other ammo manufacturers reported an up swing in OOB discharges with MP-15 rifles?

They need someone who speaks English to write their advisories. The problem is "...evidenced by a LACK OF DAMAGE to the chamber and barrel extension" ??? They're saying that if everything looks OK, there's a problem!?

There are two sentences.

"WOLF Performance Ammunition has received notifications relating to Smith & Wesson M&P-15 rifles that are discharging out of battery which is evidenced by a lack of damage to the chamber and barrel extension. <----------- This shows that the rifle’s bolt did not lock into the barrel, yet the hammer was still able to strike the firing pin to detonate the cartridge and cause a failure."

My guess is that not everything "looked ok" ;). Blown out magazines and probably receiver failures.

For inquiries or challenge their conclusions, Wolf can be reached at (888) 757-WOLF (9653)

Is there something unique about an M&P 15 vs a normal milspec AR-15? Cause the bolt carrier and components should have dimensions such that the firing pin is not long enough to touch the primer unless the bolt is cammed to the locked position.

The firing pin is housed in the bolt. As long as the case head is 'flat' against the bolt face, the primer is in reach of the firing pin--regardless of whether the bolt has rotated and locked into the barrel extension, or even if bolt is only partially into the barrel extension.

No, it doesn't. If you have a milspec AR 15 pull your carrier out and try. If it is the correct dimensions for all the parts it the firing pin by design CANNOT extend past the bolt face until the carrier is fully in battery.

Ned Christiansen did a cutaway to illustrate the fact. That bolt is locked into the lugs but the carrier is still slightly OOB.

You can read about it here.

How does AR15 bolt carrier prevent hammere-follow slam fire, when using hammer with notched top? - Page 1 - AR15.COM

?? For The Experts: Out Of Battery Discharge - What Prevents It? - AR15.COM

So my question still is, what makes the M&P different? Or is it just BS and bad ammo that Wolf is covering up.

I'll pull a BCA and take a look at it, eventually. I haven't seen many actions that aren't capable of ignition, less than 100% in battery.

Does the M&P carrier have the internal structure cited in your references?
 
There's mention on another firearm forum about a conversation with
"James" of Wolf:

A rep named James stated with all .223 Wolf sells they will usually get a couple reports total per year regarding out of battery discharge for all brands of rifles. But this year they have had seven out of battery reports with the M&P 15. James said it includes both steel and brass cased ammo.

Posting links to items on sale Amazon and Office Depot gets "infractions" here, so you'll have to use your Google-fu.

You are most likely quoting me on TFL which is referencing ChattanoogaPhil from this thread.:eek:

Look up post #11

I am with BlueOvalBandit on this one. An OOB firing cannot happen in a AR15 with a Milspec bolt that is within spec and not damaged in some way. That does not mean it never happens but when it does the rifle, specifically the BCG, or the ammo is out of spec.

If you look at Ned Christiansen cutaway photo provided by BlueOvalBandit you can see that in order for the ammo to be the cause of the OOB firing the primer would be so proud of the case that there is almost no way you would not notice it when loading the round into the magazine. IMHO.
