The only "negative" experience I have ever had with Winchester occurred two years ago in July 2012. I had a brand new Savage model 12FV chambered in .22-250 with a 26" bull barrel but, due to the ammo scarcity at the time, I had difficulty finding ammo for it. I finally located some at a Walmart about 75 miles from home, so I made the drive and bought my store imposed limit of three boxes. It was Winchester 55 grain Varmit X in .22-250, a line that I had never used before. As luck would have it, all three boxes were from the same lot number, 55GD80

Two days later I finally got a chance to try this ammo. Well, upon firing the first round I noticed that the muzzle blast was much louder than what it should have been, plus recoil felt more like a .300 Win Mag than a .22-250. When I tried to lift the bolt, I discovered it had seized. The bolt would stiffly unlock and lock, but not lift. I was finally able to open it by hitting it with the heel of my hand. When I tried to pull the bolt to the rear I also had to use the heel of my hand again. When I ejected the fired case, I discovered that the primer was totally missing. IT had apparently disintegrated and the case head was blackened all over. No other visible damage could be seen on the fired case.

Well, believing that factory ammo was always safe and being ignorant of pressure signs at that time, I "assumed" that particular round was just a fluke anomaly. I checked my gun out as best I could and could not find anything wrong, so I went ahead and fired the remaining 19 rounds of the first box. The same situation happened four more times.......a total of 20% out of one box of ammo! I immediately stopped firing, gathered my equipment and went home.

Once at home, I took the rifle to my workshop to examine it under brightly lit magnification. Although I could not find any obvious damage to the receiver and other parts of the action, I did notice a chunk of metal missing from the face of the bolt. It also appeared to have been scarred. I got online and found a customer service number for Winchester-Olin. I called them and explained what had happened to the customer service agent.

The next day UPS came to my front door and picked up the box of fired cases along with the two unfired boxes of factory ammo. While waiting for Winchester-Olin to examine the fired cases and unfired ammo, I took my rifle to a local gunsmith. While he was checking out the rifle, his no-go gauge literally fell into the chamber. He used several other types of gauges to take various measurements, then compared readings to various reference books. He told me that the rifle was unsafe and not to fire it any more under any circumstances. He explained that the chamber had been lengthened and also bulged outward due to very excessive chamber pressure. He further told me that I had been extremely lucky that the rifle had not literally blown up in my face!

When I got back home, I again called Winchester-Olin to explain what I had learned. Their customer service department told me how to package the rifle to return to them for inspection. A few days later, UPS came to my house and picked up the rifle. A week or so after that, I received a check for the purchase price of the ammo, but no word on the status of my rifle. Days later I received an email explaining that a recall would probably be issued for that particular lot number of ammunition - .22-250 Winchester 55 grain Varmit X, lot #59GD80.

Winchester was unable to repair my rifle so they forwarded it to the Savage factory. Savage ran multiple tests but could not salvage the barrel, so they replaced the barrel and billed Winchester-Olin for expenses.

The bottom line? While overall I was very pleased with Winchester's customer service and the repair of my rifle, I was extremely disappointed it took four (4) months to do so. Plus, I have followed ammunition recall listings since this incident, but I have never seen any type of recall notice published for that type and lot of ammunition.

So what is the moral of this story? NEVER ASSUME that factory ammunition is always safe because there is always an inherent risk. It may be a very small one, but it is always there. Also, whether you reload or not, LEARN to identify the various signs of excessive pressure.....it might just save your life or that of someone you know. I was lucky because I lived to tell the tale.
 
Also, if your gun goes boom more than it should and stuff jams up, stop shooting and get it checked out.
 
Also if you're gun goes boom LESS than it should immediately make sure that the bullet left the bore. If you happen to fire another round and the bullet from the first shot has not left the bore you might end up with a blown barrel or chamber. Neither are good things.
 
Any time you fire a shot and the action doesn't respond exactly as it had on the previous round, it's time to disassemble and have a looksie. It may be as simple as a lack of lube or a hidden burr, or as in your case something more serious. Either way it's bad news for your finely tuned machine.
 
Actually, while 4 months may seem excessive, it probably was pretty quick turn around in their eyes. When you factor in all the calls and emails that went on inside Winchester, and the transit times back and forth, and the testing and evaluations that were probably performed in their labs, it adds up to a lot of time. I imagine they get many, many complaints every day and have to wade through them to figure out which ones are legit and which ones are people trying to make a buck.
I sure am glad nobody was hurt. I personally have never had anything like this with factory ammo.
 
There are some people who think the case is a strong pressure vessel, like a propane torch bottle, but it is not. A cartridge case is operating at pressures that would rupture a propane bottle and because of the massively higher pressures, it must be fully supported within the chamber. If too much case head sticks out of the chamber the sidewalls of the case will rupture.

These are from Chin's Machine Gun Book.

In my opinion, if the gun chamber headspace was excessive, leading to too much case head protrusion, that is a fault of the gun, not the ammunition.
 
Slamfire1, your post makes perfect sense but how would you know that on a brand new rifle you just purchased but had never fired. The incident that happened in my original post above was the very first time I had fired that rifle!
 
I don't completely trust factory ammo, which is why I reload. The only mishaps I've ever experienced was in fact with factory. I know most factory is safe to shoot, but considering it's mass produced, the likely hood of coming across a bad lot is far more likely. than me making a mistake with my loads.

Anyone ever blow up a rifle?

Not yet, but I have a few thousand rounds of .30-06 and a National Ordnance 1903A3. Haven't decided if I want to keep shooting it or not from rumors I have heard.

You know what they say: play stupid games, win stupid prizes
 
Anyone ever blown up a rifle?

No, not personally. Did get to see, hear actually, a guy blow one up recently. A brand new Rock River AR.
Lower receiver bulged out. Upper receiver trashed. As in pieces all over the ground.
Shiny new gun shooting cheapo local re-manufactured ammo. Go figure.

Thank god the kid was OK, just black marks on his hands.
 
Yes.

Old 1960's Golden State BM-59 that apparently used a re weld M-1 receiver and was not properly heat treated. The hump shattered and was just gone. Based on what drifted to the surface of my right hand for thirty years it was reduced to sand sized particles.

I always wear eye protection.

I had a DCM (pre CMP) Garand slam fire on me during a mach, destroying the gun and tearing my hand up pretty good. My hearing hasnt been the same since either.

Luckily, the gun stayed together for the most part, but Im lucky it wasnt in my shoulder when it did let go. The back of the receiver was blown off, as was a big chunk of the stock. My head most likely would have absorbed that, had it been on the stock.

Ammo was match issued LC69.
 
If we are going to do "did not happen to me but, I seen it"

I have seen M-16A1s shatter or break extractors and one that the bolt cracked on. In the case of one of the extractors it headed off to parts unknown after kicking up dirt to the right of the rifle.

A few years ago a friend of mine had his Remington 552 22lr blow up. I was sitting next to him at the time. Blew a piece out of the side of the receiver and stuck it in my arm thru a flannel shirt. We recovered the case as it was still in the chamber. Did not appear to be an out of battery event. One side of the rim was completely gone and the side wasmsplit to the mouth. It did not display the typical bulge that occurs when a round fires before the bolt is closed. Sent rifle and box of ammo. Remington said they found nothing wrong, but, send in the rest of that lot of ammo and you can hqve new gun. Oh , and sign all these papers just as a formality. No real harm done so he took the new rifle.
 
A guy at my range had his AR blow up the other day. I didn't see it happen but I saw the aftermath. It was the weirdest thing.... The BCG puffed up and had linear cracks, the magazine blew out and there was damage to the receivers. However the really weird thing in my mind was that the bolt lugs were still partially locked in battery. It looked like the pressure might have gone through the bolt face into the BCG and then blown the rest apart.
 
There are some people who think the case is a strong pressure vessel, like a propane torch bottle, but it is not.

I don't have exact numbers but propane bottles and even 20lb tanks are only "realitively strong" they will hold a few hundred PSI or more than say a soda can or balloon. Both are under 1/8" thick, Acetylene tanks are a bit thicker but still "low pressure".

"high pressure" tanks, like Oxy, argon and co2, that hold a few thousand PSI are still not that thick even for the diameter. A tank with an ID of 8.5 inches or so are still only 3/8" thick or so.

Consider going from 2000 psi to 20,000 or more and "all bets are off" and they are not made from brass either.

Throw a live round in a fire (ok don't actually do that unless you do it in a controlled environment) and the case will rupture like a piece of popcorn.
 
I had a guy blow up a Ruger #1 chambered in 7mm STW in the stall right next to me- about 2 rounds after he let me shoot it. (hand loads) He left bleeding but nowhere important. I was at my bench, and from the sound of his report I knew something just went wrong. The brass flowed all the way around his falling block & shattered his wood stock, it was impressive.
 
You came out pretty well for the experience.

1. Guy at the range shoots lefty now since his rifle DID blow up on him, bolt blew right out the back and he lost his right eye in the process.

2. You were actually blessed with Remington picking up the tab. Usually, it is a finger pointing event with both manufacturers pointing at each other for blame.

Four months, not an issue when one thinks about what could have happened.
 
I blew up an Ishapore 7.62x51 Enfield with a factory overcharged round. Factory replaced the rifle and paid for my ammo ( a case of it ).
 
Fortunately, I heard enough cautionary tales when I was young so that I worked up handloads. What got me in a bit of trouble was not taking Ken Water's literally in his Pet Loads artlcle on the 6 mm Remington. Being a bit naive, I took his articles and load data to be sort of like loads in a manual.

They are not. Mr. Waters was a very good engineer and scientist.

Lesson 1. When he said starting load, HE MEANT IT.

Lesson 2. He always explained that all rifle actions have a different amount of strength and may tend to be elastic under pressure (stretch under high pressure). He also said his loads were for the specific rifle used in testing. HE MEANT IT.

Now to the circumstances that did not lead to a damaged rifle or shooter, but were disconcerting and highly instructive.

I took some of his data developed for a Remington 700 and backed 10% off a load listed as: MAXIMUM LOAD! DO NOT EXCEED! Being young and stupid, I thought that since this will work with a loading manual, it would be fine. I put the first round into my beloved Remington Model 788. This is a much weaker action than the 700. It is marvelously accurate, but the locking lugs are in the rear and the bolt will move around under very high pressure. I took careful aim, and squeezed the trigger. The rifle fired, and gunsmoke began to pour out of the gas vents. I had to hammer the bolt open with my hand to extract the case. The head was nicely flat and the primer was perforated.

I took the rest of the handloads home, pulled the bullets, and weighted the powder. The load was as I had logged it. I burned the powder, reseated the bullets over a pet load of my own, and was relieved when the first three went into a half inch at 100 yards--just like it always did when I did my part.

That instance happened about 35 years ago, and led me to do a lot of thinking about the pursuit of velocity. After very carefully examining the trajectories at various velocities for over a half a dozen high velocity rounds, and then comparing my chronograph numbers to published figures for several factory and handloads, and then looking at the performance of bullets on game I decided several things.

1. It is always better to be conservative with load data. You can't shoot if you can't see.

2. Velocity isn't what many people make it to be. I have seen several loads for "high velocity cartridges" that are 150 to 200 fps lower than published when fired in a real gun, that is, not a pressure barrel (one, alas, is my 270, I think it has a slow barrel. Accurate, but slow). As a rule of thumb, 100 fps gets you an extra 10 yards of point blank range.

3. If you are going to worry about anything, worry about accuracy. Bullet placement trumps just about everything when you are shooting at a target. In both hunting and competition, you are judged by where the bullet hits, not how fast it the bullet is going when it hits the target.
 
Yup, blew up an M4 on the firing line during a night fire stage when I was at CATM school at Lackland AFB. Fired one burst, pulled the trigger a second time, one round went off then something hit my left wrist. I stopped for a moment to look down and seen my mag puked it's spring, floorplate and ammo on the ground and that there was a black carbon mark along my wrist. We called a cease fire and closer inspections showed the upper was bulged as well as the magazine well on the lower. I also think the bolt carrier had cracked too but I'm not sure since that was over 10 years ago now. I DO remember though that Lackland has had a love-fest for that Federal frangible crap ammo and that's what we were firing.
Apparently while writing up my statement on the events that happened, the NCOIC was in and was yelling about condemning the whole lot of that ammo. Hmm, sounds like this wasn't the first problem they had with this junk!
I've heard it said that if you shoot long enough, you will have a weapon fail blow up sooner or later. I'm just damned glad that when my time came to blow up a weapon, it was one of the government's rifles and not one of my own. :D
 
I haven't shot factory ammo in many years since I reload. I try to be careful to a fault and only charge cases between 92% and 98% of max load data. That seems to be the area where the loads are most accurate or they are more accurate than I am.
 
I had a DPMS LR-308 that fired a Rermington factory round before the bolt closed. It blew straight down through the mag well, traumatically disassembling the mag but failing to detonate the ammo therein or damage the receiver or even the bolt.
