out of battery detonation (shards of brass)

[vdirico]

Was the rifle in question a Performance Center edition? I'm have observed more OOB discharges on the PC guns, due the the tighter chamber I guess. PC rifles and Remington ammo seem to be a recipe for disaster.

The two rifles are not Performance Center edition... I am not aware of the difference, can you please tell me?



I have one of the 1400 round Remington Golden Bullet 22lr buckets sitting in my safe thanks Vinny

Just to give you another opinion. I have shot several thousand rounds of Golden Bullets through my two with no issues at all. They are a bit inconsistent, but they all function.

Promo Ammo!

Before COVID I shot weekly club style Gallery Bullseye. Because these weren't Official NRA matches I shot up a lot of "Promo" ammo. (The cheap stuff, saving the good stuff for NRA matches)

About once a year I experienced a "blow out" that looked a lot like what I'm seeing in your pics. These were obvious over pressure "kabooms" since they were lauder and felt like a 9mm in my M41.

I just chalked it up to poor quality control. This Winchester promo ammo was so bad that rarely did anyone shooting it go through 100 rounds without a dud, squib or failure to go into battery!

Sorry to be tardy with my response. The Performance Center rifles had a longer, fluted barrel with a "match" chamber. The tighter chamber can cause the round to not chamber fully especially when the rifle gets a little dirty. The PC rifles seem to be less prone to OOB failures as they get broken in.

This is from S&W maybe related.

IMPORTANT! M&P15-22 CONSUMER SAFETY ALERT AND INSPECTION PROCEDURE

DESCRIPTION - Please Read This If You Have A M&P15-22 Rimfire Firearm.

PRODUCT AFFECTED:
ALL models of M&P15-22 rifles and pistols manufactured before February 1, 2019.

STOP USING YOUR M&P15-22 UNTIL IT HAS BEEN INSPECTED AND YOUR BOLT REPLACED (IF NECESSARY).
Smith & Wesson has identified two M&P15-22 firearms from recent production on which the breech face counter bore depth was not within manufacturing specification. In those firearms, the lack of depth may allow the bolt, upon closing, to crush the rim of the case, causing the round to fire, cycling the bolt, and potentially resulting in multiple discharges without depressing the trigger. This issue can occur in the following two scenarios:

1) With a loaded magazine in the firearm and the bolt locked to the rear, depressing the bolt release to allow the bolt to drop freely may ignite the round as the bolt closes without engaging the trigger and with the safety selector in either the safe or the fire position, and may also result in multiple discharges.

2) With a loaded magazine in the firearm, bolt in the closed position and a round in the chamber and the safety selector in the fire position, depressing the trigger will cause the round to fire normally, however as the bolt cycles, the next round may be ignited by the bolt crushing the rim of the case as it closes, causing multiple discharges.

We believe that these are isolated incidents, however, any unintended discharge of a firearm has the potential to cause injury. Therefore, we have developed this inspection procedure to ensure that all products in the field are safe to use. We are asking customers to perform the following procedure and to refrain from using their M&P15-22 until the bolt has been inspected and replaced as necessary.

DESCRIPTION OF THE PRODUCT INVOLVED:
The out of specification condition has been found only in bolts that were recently manufactured. While our investigation suggests that the incidents are isolated, we have established this inspection procedure as a precautionary matter to ensure that all M&P15-22 firearms in service meet our design specifications. We are asking consumers of all M&P15-22 firearms manufactured before February 1, 2019 to inspect their bolt for this condition.

REMEDY/ACTION TO BE TAKEN:
The bolt from your M&P15-22 must be inspected to determine whether it exhibits the condition identified in this notice. To determine whether your firearm is affected by this condition, please inspect your firearm by following the inspection instructions provided here.

Crazy! lol!

 

[moosedog]

Glad you were not injured. It can happen, and not just with the S&W MP 15-22. Always wear that eye protection.

 

[CH4]

What ammo were you using?
I see it a lot in 22 autos with dirty or tight chambers firing out of battery.

 

[minconrevo]

Brittle brass will blow out at the rim on firing. Had this happen a few times over the years. Ammo maker will typically test then replace if this is the case. Brass may pass QC on shipping but fail 3 or so years later.

Any .22LR can blow out rims on firing with bad casings.

Recently have seen a few .22LR "hot" charged. Also some way underloaded. The other day saw one jam the bullet in the barrel. All were US made ammo, produced in last couple years. Not the best times at the ammo plants these days.

Not just recently, although not so bad as to blow case heads or stick bullets.
My Smallbore Prone friend is generally happy with SK Standard Plus, leaving Tenex and other High Priced Spread to the hotshots.
He can hold the ten ring with it but says if it goes BANG, he knows he will be likely to have a high nine, if it goes Ptooey, he knows he will have a low nine at best, maybe worse.

 

[MJK-MOD-547]

I had it happen to me with my Colt/Walther rail a couple of times in one brick. It's a good thing I had my shooting glasses on because one of them hit me in the face and glasses.

By the sound of them when they went off, they were hot loads.

Blowback semi-autos have the capability to fire out of battery. How mush out of battery depends on fitting and tolerances,

It is not common because the vast majority of the time, everything works as it should. However, if something prevents the spring from being able to push the breech totally in battery, problems will occur. This could take the form of debris fouling the mechanism, or, with rimfire, excess wax on the bullet preventing full chambering.

Keeping the gun clean is an important safety consideration.

I am fortunate that one rimfire semi-auto I have does not (so far) fire out of battery. It does stop firing when debris builds up. Much better for it to stop working than fire out of battery, but that cannot be counted on.

 

[Hank Dodge]

I have seen quite a few 15-22 have out of battery failures. Often the extractor is also missing when inspected after. I don't know if the extractor is failing and somehow getting caught in the action impacting the primer. Or, if the out of battery ignition is somehow blowing out the extractor. Either way, it is a common enough occurrance that I was not at all surprised by your post....

 

[max503]

What rifle did that? The rimmed case suggests a lever gun, but there are semi-autos out there using rimmed cases.

Perhaps the firing pin was stuck forward due to fouling or rust. I'd have your friend clean inside the bolt and then test fire in a safe place.

I noticed (while working the action, unloaded) that my Rossi lever action will drop the hammer if you pull the trigger when the action is not fully closed. I've only done it with my thumb cushioning the hammer-drop. Never fully dry fired it that way. Kind of scary if you think about it.

Although the OP hasn't said the brand of ammo, I quit using Remington .22 LR ammo many, many years ago. Mostly because it was unreliable and inaccurate. As far as Remington centerfire ammo is concerned, I find the brass weaker than Federal, Winchester, CCI, etc. With reloaded brass, I've had more cracked cases and blowouts with Remington by far.

Both of my 15-22 s will drop the hammer ant time the trigger is pulled. In b
attery or out. Gotta keep it clean guys. Apparently they don't have safeties.

As far as I know the only 22lr rifles that I own that WONT drop the hammer when out of battery is my Marlins. The Ruger 10-22 , the Remington 597 and the S&W 15-22 will. The Marlin 795 also wont fire without the mag.
