I was acting as SO for a shooter in a stage of a 3-gun match yesterday. In the middle of the stage (after 8 or so rounds of birdshot) 2 slugs were required. The shooter loaded 2 Wolf slugs, attempted to fire, *click* (we all thought it was simply a dud)... he quickly performed a malfunction clearance, ejected the first and chambered the next slug, aimed, pulled the trigger, and BOOOOOM. :what:

For a second the shooter didn't notice the burst barrel and was preparing to load up with birdshot and continue with the stage until I stopped him (I think he would have noticed something wrong once he brought the gun up and sighted down the barrel...) :eek:

First thing I said to him (after "stop! Stop!" and safety checking/chamber flagging the weapon--I suppose it could still fire, theoretically--and asking if he was hurt, which he wasn't... otherwise he probably would have noticed something was wrong ;) ) was "is it possible you chambered a 20 gauge first by mistake?" It was kind of chaotic/confusing for a minute, as you can imagine.

It wasn't until afterward that we looked at the hulls on the ground and noticed they were both empty. Until that point we assumed he just ejected a dud cartridge as you normally would during a malfunction clearance. It all happened very quickly. One of the guys waiting to shoot said he thought it was strange that the "dud" that was ejected first was smoking on the ground, but he didn't really have time to think about it. It was just one of those things you only realize after it happens. And by the time he could have said anything the shooter had already pulled the trigger on the next round anyway.

The shooter had borrowed the shotgun from his brother, who wasn't very happy, understandably. Thankfully nobody was hurt. I was almost directly behind the shooter, a position which probably protected me from any schrapnel, which looks to have gone up and to the right from what we could guess.

From what we could tell the magazine tube wasn't damaged, but obviously the forend was destroyed. The owner says he's going to attempt to get compensated from Wolf (and there were many witnesses). It was a bit scary because we all just heard a "click" as the hammer fell, not a "pop" that would indicate an obvious squib. I suppose it's possible that a slow/late/incomplete powder burn occurred quietly just before he racked the bolt, and thus had just enough power to drive the slug into the barrel. Or maybe the round had very little or no powder and the primer's 'pop' was insulated by the barrel and the slug in front of it.

I've gone over this and over this in my head and tried to determine what we could have done better, and short of examining every *click* "dud" cartridge and examining the bore to ensure it's clear before the next shot is fired, which is obviously not the norm in a "competition" environment... I can't think of anything that would have prevented it in this specific case. If there had been an obvious "pop" of the primer we all would have stopped him, as has happened before (primers loaded backwards, etc.). But tactical/combat/competition malfunction drills emphasize clearing the dud/malfunction quickly and moving on.

In any case... in my private/informal shooting I'm going to take a good look at the bore and the shell after a "dud", before I load another round. Be careful out there, guys. Wear your eye protection. :cool:

Good to hear no one was hurt.

I also think it's a bit of a testament to modernish metal working and firearm design that so many catastrophe firearm failures to not result in serious injury to the shooter or bystanders.

This is also a great reminder of why to always wear eye pro!
 
May be hard to tell now especially if you don't have the gun, but is the reciever damaged? It almost looks like he could just change out the barrel/mag tube/forend and be good to go.
 
I didn't see any damage to the receiver, and the bolt still moved freely.

Paul, I and several others commented similarly... rather than simply grenade into a million fragments, the barrel stayed in large pieces and for the most part, held together (though "peeled").

I'd use a 930 without reservation. I'm not so sure about wolf slugs. However any mfg can occasionally produce undercharged or squib loads. The really high-end "hand inspected" stuff may be less likely, but I don't have any statistics on that.
 
Also FYI, a couple of people have asked me whether anyone was wearing electronic earmuffs and maybe could have heard the pop of the primer better.

I was wearing electronic muffs with the volume adjusted to "normal" speaking levels or perhaps a bit louder (and several of the other shooters in my squad were wearing electronic muffs also). It was definitely a "click" and not the "pop" that you would expect from a squib.
 
Glad no one was hurt.

I had this happen with a rifle (!) once. The ammo manufacturer replaced the gun. The "price" was returning the gun and the remaining ammo to them at their expense so they could review/study the situation.
 
I don't shoot timed competitions - but when we do have someone have a round go "click" or "Pfft", they know to hold the muzzle downrange for about 5-10 seconds in case there is a delayed ignition. That happened top a friend and his lovely Belgian Browning, held loosely for the moment, flew out of his hands and hit the concrete. He is fortunate no one got hurt, and his gunsmith back in England could repair the stock damage
 
Whoa...


Glad everybody's alright, hopefully Wolf doesn't have any problem with replacing the SPX. Yeah modern firearms really beat out the death traps of a couple hundred years ago, which were orders of magnitude better than the crude sticks and tubes of a few hundred years ago.
 
Wolfs Response

Thanks 1K for posting this thread. As 1k knows this shotgun belongs to me.
I have contacted Both Wolf Ammo Co. as well as Mossberg Both have been very helpful and gracious. Despite the issues I am having with Wolf Ammo I am impressed with the manner they are handling the situation.

Here is the response from Wolf:If you give me your name, mailing address, the caliber, amount of remaining ammunition you intend to return, where you purchased the ammunition from and the lot number, (stamped on the inside of the individual boxes), I can send you out prepaid UPS tags in the mail, they will allow you to return the ammunition to us at no cost to you. As soon as we receive the ammunition, we will issue you a refund or exchange, which ever you prefer. However, if you prefer a refund, please include a copy of the invoice inside the case to be returned, otherwise an exchange will automatically be given.



*As far as the damage to your gun, please go ahead and have your gunsmith put together a repair invoice along with a mini statement letting us know that it was in fact our ammunition that caused the damage, please include this paperwork along with the spent casing in with the ammunition you have to return, once ALL the above items are returned to us, we will go ahead and cut you or your gunsmith a check directly.



Thank you for your time,

Continue to let us know how Wolf's CS department follows through. Personally, I've never bought Wolf, but if they're quick to alleviate this problem, then I would have no problem giving them a recommendation.

I shot my SPX for the first time today and was completely enamored. I'd hate to think of her with a burst barrel.:(
 
Definitely. It's a cheap way (for them) to spread good will and positive reviews. I wish more companies would behave similarly.
 
There are a bunch of studies in the medical area that show people are overwhelmingly less likely to sue if they get an apology and some fair compensation right up front, rather than stonewalling and legal talk. I think the firearms industry realized that a long, long time ago. ;)
 
Great that your ammo company is fixing your gun after you negligently discharged it after failing to check it after your ammo failure.

You never discharge a weapon after such an incident without verifying first, that it wasn't a squib!
 
If I didn't hear a pop, I would rack and continue as fast as possible, every time.

Good on Wolf for doing the right thing.
 
I've never had a bore obstruction, but I used some really old primers one time that gave me a lot of squib loads. I was also doing rapid fire when I discovered the problem, but not for competition.

The first round really surprised me with a light pop and no recoil. I could see the pellets leave the barrel at about arrow speed. I stopped shooting, pulled the barrel off and checked before continuing. After two more squib loads (and pulling the barrel to be sure it was clear) I bagged the rest of the shells and disassembled them later to reuse the components.

I suppose the yellow residue in the primer tray should have been a clue, but they had actually been doing pretty good in my muzzleloader. I soaked the remainder in water and threw them out.

This one real failing of a pump vs an autoloader. The auto has a built in mechanism to alert you to a bad round. The pump doesn't, I could have easily pumped in a new round no matter what the squib did. The same can be said for revolvers too.

This also points out a weakness in most immediate action drill training. In the Army they never mentioned the possibility of a squib load. If a casing was ejected and the chamber looked clear we were supposed to chamber a new round and fire it.
 
Yes. I have seen black powder shoulder arms burst their barrels when fired with blanks and an inadvertently plugged bore. Sometimes those mid-barrel bursts take big bits of the left hand with them.
