Priming Kaboom — Primer Flash Sets Off Multiple Primers in Tray

primer flash explosion Hornady handheld primer tool kaboom

Here is an important safety reminder for readers who employ hand priming tools with trays of multiple primers. In this instance a primer detonated while being seating in a pistol cartridge case. This caused a “flash-over” which instantly ignited multiple other primers in the tray. That, in turn, caused a small explosion which broke the tray and Hornady Handheld Priming Tool. The user, a Forum member, posted this report this morning in our Shooters’ Forum.

primer flash explosion Hornady handheld primer tool kaboomReport by Forum Member about Primer Flash-Over Incident
I had a small scare the other day while reloading. My experience might be a helpful reminder to people to keep safe and follow proper procedures and not be sloppy.

A primer popped (went off) when being seated and (while hot) flashed over into the tray causing other primers in the tray to detonate. That, in turn, broke my Hornady Handheld Priming Tool and injured my hand.

Here is my loading area after the incident. Note the damage to the hand priming tool. I’m not not sure where the rest of the pieces are.

Injuries to User — Multiple Cuts on Hand and Forearm
This photo shows the resulting cuts to hand. Fortunately they seem superficial. Note — I was wearing latex gloves so my hand had some protection.

The blast also blew my glasses off my face and they landed about six feet away. Be careful folks and wear your eye protection! EDITOR: Guys — This is yet more compelling evidence why handloaders should always wear eye protection!

More Details — Primers Were Federal LP, Case Primer Pockets Had Been Checked
The forum member noted: “Just in case people are interested, I didn’t notice anything different from usual. Cases were Privi Partizan (PPU) factory brass on their fourth firing. The primers were Federal Large Pistol. The cases had been ultrasonic cleaned and the primer pockets checked prior to priming. I had primed around 50 cases during this session before the accident.”

Here is a close-up of “flashed” primers — note the empty but dented cups and triangular “anvils”:

This incident happened using a Hornady Handheld Priming Tool, as shown below.

Two other Forum members reported feeding issues with this particular handheld priming tool and one other member, Kiwi Greg, suffered a multi-primer detonation causing injury: “I had the same thing happen a few years ago now with the same Hornady hand primer with 50-75 [Federal 215M primers] in the tray. Made a bit of a mess of both my hands, blew primers and tray all around my large workshop. Scared the [heck] out of my employee who was near me at the time. Some stitches, bandages and it was all good, [but with] some wicked scars… I think a primer had turned side-on when being put into Bertram .408 CT brass which had nice tight pockets and required more force than usual. I use RCBS [priming tools] now with a flat bar that slides across to prevent sympathetic detonations. I hadn’t heard of it before, but found out it wasn’t that uncommon after it happened.”

Don’t Kill Yourself — Bore Obstructions Cause Nasty Accidents

Obstructed Barrel Explosion Accident kaboom
Above is a sectioned barrel showing an 80gr Sierra that was fired in a .223 bolt action with a cleaning rod in the bore. Both the bullet and the rod are still in the bore.

A Negligent Shooter Gets Lucky
“Here we have a story so filled with negligent acts that I can only marvel that the shooter survived the experience. The photo and narrative were provided by the gunsmith who took in the repair job, my comments are in italics. It’s worth reading, we can’t get enough safety warnings in our hobby.” — GS Arizona, Rifleman’s Journal

Description of Incident (with Commentary)
The shooter had a stuck case in his .223 chamber. The stuck case was actually a loaded round that didn’t fire. It wouldn’t extract because it was a .222 case that got mixed in with his .223 brass. [He had loaded the wrong brass.] I saw the loaded round with an 80gr bullet in it and a light primer strike. Negligent Act #1: Wrong brass was mixed in with the brass being reloaded.

The shooter removed the stuck case with a 3-piece aluminum rod. Negligent Act #2: Hammering out a loaded round with a cleaning rod. People have been killed doing this as the round can fire and drive the cleaning rod right into you. I remember one such incident about 5 years ago, the shooter was pounding out a stuck round, the cleaning rod went right through him, he didn’t survive.

The shooter didn’t notice only two segments of the cleaning rod came out when he removed it. Negligent Act #3: If you put anything at all down the barrel of a rifle you’d better make darn sure you got it all out before doing anything else!

He then chambered another round and fired it. Negligent act #4: If you’ve had a barrel obstruction of any kind, and if you’ve put something in the barrel, look through the barrel before proceeding! Within the past two years I know of an incident in which a benchrest shooter was killed in exactly this manner. The pressure built up and the rifle bolt came out of the receiver and into his chest.

The shooter is ‘OK’, but did not escape unscathed. He said there was a huge explosion and after regaining his senses found he was bleeding heavily from his forehead. The blood was thick enough that it ran in his eyes and he couldn’t see. In his words “I thought I was going to die”.

He has what looks like a pretty deep cut about an inch long on the side of his head, right in line with his right eye starting where the eye socket turns out to the side of the skull. And no telling what he’s got in the way of brass particles embedded in his forehead.

He was shooting on private property, and was alone when this happened. Negligent Act #5: Don’t shoot alone! Accidents happen, this is just one more example. If we could predict accidents, we wouldn’t have them. Always shoot with at least one other person.

He managed to get the bleeding stopped, or at least under control, packed his car and drove himself home without seeking immediate medical attention. Negligent Act #6: This one could have cost him his life after being lucky enough to survive the incident. There’s no way to know what’s happened just after an incident like this. He should have been at a hospital getting checked for shrapnel in the head.

The rod and slug could not be driven out. Since the barrel had a high round count there was no point in trying to salvage it. Note that the aluminum rod is expanded to a tight fit in the bore for the first couple inches. The base of the bullet is a little over 2″ from the mouth of the chamber.

What we’ve seen here is negligence and an absolute indifference to the established rules of safe reloading and gun handling, from start to finish, capped off with the shooter’s foolish avoidance of medical treatment. This shooter is lucky to be alive, but he’s surely used up all his luck. Don’t assume you’ll be so fortunate.

AR-15 Critical Failure — Bolt Breaks into Two Pieces

AR15 AR-15 Bolt failure Broken AR Bolt Police Department

A while back, our friend Dennis Santiago was conducting training for a Southern California Police Department. During a training session one of the unit’s AR15s stopped functioning. The problem — the bolt in the AR rifle broke in half. Dennis states: “They ran the gun dry, broke for lunch, shot it again. They don’t like that. I personally like to flood the bolt wet with lube on training days. It prevents stuff like this. Given that, it’s a simple remove-and-replace fix.”

AR15 AR-15 Bolt failure Broken AR Bolt Police Department

Here are some of the more interesting comments about this parts failure — an AR bolt that literally sheared in half:

“If I was a betting man [the steel] wasn’t made by Carpenter Steel. They are one of the few companies that use the correct [milspec-steel, C-158] called out on the drawing which they coincidentally developed. Most of the other companies that make [AR Bolts] use different steel with the same heat treat specification as what is called out which gives them the potential of being a little on the brittle side at the upper end of the tolerance. When it comes to the AR platform, bolts are probably the only part of the entire gun where I must admit to being a little bit of a brand snob.” David O’N.

[Editor’s Note: Actually Carpenter Steel does not make AR bolts. They are a steel supplier, and yes Carpenter did develop the original C-158 steel for AR bolts. Here is a contrary view, claiming that AISI 9310 Steel is actually stronger than milspec Carpenter C-158: 9310 Steel for AR Bolts.]

“Dry bolt and carrier shouldn’t cause that. Looks like a big pressure spike. What kind of ammo…?” Guy G.
Reply from Dennis: “55gr factory ammo. Piles of it.

“Is that the new two-piece bolt everyone’s been talking about LOL?” — Darren R.

“Let me guess…the PD called you in cause they didn’t know why it stopped going ‘pew pew’?” — Jim O.
Reply from Dennis: “I was there today for qualifications. It broke during the rifle phase. Simple enough to fish the bolt parts out of the action. The training didn’t miss a beat. I have an armory full of the things.”

Out-of-Battery Blast Breaks Rifle and Bones in Shooter’s Hand

out of battery kaboom bohica 50 bmg ar15

As posted in the Calguns.net a few years back, there was a nasty out-of-battery firing incident involving a BOHICA Arms .510 DTC AR15 upper. The cause of the out-of-battery firing is not certain but it appears that the ammo was not sized properly and the firing pin may have been stuck in the extended position. As a result, the round went off before the bolt was closed with the lugs seated. In the process, the bolt handle broke off, as the bolt retracted violently, actually ending up outside the bolt raceway.

out of battery kaboom bohica 50 bmg ar15

The shooter was badly injured, with broken bones and ligament damage to his left hand and tissue damage to his right hand. The shooter was holding the rifle with his left hand near the front of the chamber where a gas vent was located. Gas and shrapnel existed the vent hole causing the severe injuries to the left hand.

From range reports, it appears that the shooter had been struggling to chamber previous rounds, and was having trouble closing the bolt. After talking with one of the rangemasters, a poster on AR15.com reported: “The guy was using new reloads that weren’t exactly fitting well into his chamber. [The shooter] was slamming the bolt handle with his palm trying to get the cases to lock in. The guy was also slamming the bolt forward full force from the rearmost position back and forth trying to ram the cases into chamber in an attempt to squeeze the rounds in so the bolt could close. Finally, on one of the attempts … the possibly stuck firing pin rams into the primer and explodes the round when he slams the bolt forward (zero lug engagement hence the KB) and shooter puts himself into a world of hurt.”

Lessons Learned — Don’t Try to Force Oversize Ammo into a Chamber
By all reports, the shooter’s ammo wasn’t fitting his chamber properly. In an effort to force the ammo into the chamber, he worked the bolt with excessive force. That MAY have caused the firing pin to extend or the hammer to fall without the trigger being pulled. One theory is that the trigger system may have been modified, allowing the hammer to fall from the force of slamming the bolt forward. Others have speculated that the firing pin may have failed to retract because the bolt handle was over-torqued — a safety issue listed in the BOHICA manual.

out of battery kaboom bohica 50 bmg ar15

Whatever caused the out-of-battery firing, it appears that improperly-sized ammo (or a poorly-cut chamber) was the root cause of the problems. If you go to a range and find your bolt does not close easily over the ammo — STOP SHOOTING — don’t try to force the issue. Disaster may result. To paraphrase Johnnie Cochran: “If the ammo doesn’t fit, it’s time to quit”.

Black Rifle Blow-Ups — Shocking AR 15 Kaboom Collection

AR15 AR-15 Kaboom explosion pistol powder accident catastrophic destroyed
AR15 Kaboom big photo
This shocking photo of destroyed AR-15 bits and pieces was posted on Facebook by William Walter, a firearms instructor. William said this was “The worst AR-15 blow-up I have ever seen. The case head literally atomized …you can see the brass residue on the parts. The bolt was split in two also.”

There’s nothing inherently wrong with AR-platform rifles (well, except that they run dirty). Over the past six decades Eugene Stoner’s semi-automatic design has proven its merits in military and civilian applications. You may not know, but the original AR from 1955 was a .30-caliber. The Armalite AR-10 shot the 7.62×51 cartridge. Later, at the request of the U.S. Military, Armalite created a smaller version that became the M16/AR15. The rest was history. Now there are millions of AR “black rifles” in the hands of soldiers and sportsmen.

With so many ARs in circulation, it’s no surprise that some get used by folks who don’t know how to hand-load or otherwise fail to follow safe gun practices. The AR is actually a pretty sturdy rifle, but when it’s fed bad ammo, or abused, bad things can happen. Very bad things… commonly known as Kabooms.

Black Rifle Duplex Kaboom

The American Shooting Journal (ASJ) has compiled a set of particularly extreme AR Kabooms. Compiling the “evidence” from various web sites, ASJ has published nine (9) of the most Unbelievable AR-15 Fails. Here are two of the worst “AR-15 Fails”. CLICK HERE to see them all.

Nothing but busted parts after this catastrophic Kaboom…

Another view of this sad blow-up…

These catastrophic AR failures are eye-openers, that’s for sure. ASJ cautions: “Any weapon can fail if given the wrong ammunition, faulty reloads or a plugged barrel. Always be aware of what can happen at anytime if you fail to follow common sense and gun safety rules.”

Scary Stuff — .300 Blackout Fired in a .223 Rem Barrel

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56
Photos and Facebook post by Tactical Rifle Shooters

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56

.300 AAC Blackout 300 BLK kaboom accident blowup cartridge failure barrel .223 Rem 5.56The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!

This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”

For those who MUST have a .300 Blackout, here are some things you can do:

1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.

Comments by Folks Who Viewed these .300 Blackout Disaster Photos:

“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago

“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch

“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood

“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres

“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

Blood and Gore — Injury After Pistol Powder Loaded in Rifle Case

Varget Kaboom TiteGroup Hand injury reloading fingers accident

This is a grim tale. A man almost lost the use of his right hand, and did suffer terrible injuries to his fingers. All because he picked the wrong bottle of powder off the shelf. We have run this story before, and we will continue to run it every year, as a caution to our readers. This mistake is easy to make, but the consequences can be dire. Always, always double-check your powder labels before you start the hand-loading process. If you don’t, you may not have a hand to load with next time…

Similar Labels, Disasterous Consequences
The shooter, Denny K., was assembling some rounds for his brand new 7mm-08 Savage hunting rifle. He thought he was loading with Hodgdon Varget. Instead he had filled his powder measure with Hodgdon TiteGroup, a fast-burning pistol powder. The labels are similar, so the mistake is understandable. But the results were devastating. Here’s what 41 grains of TiteGroup can do in a 7mm-08:

Varget Kaboom TiteGroup Hand injury reloading fingers accident

Posting on the Firing Line, in a thread entitled “Lucky to Be Alive”, Denny writes:

“This is the hardest post to post. I know if I had read it a week ago my comment would have been: ‘You have no business reloading’. I had everything perfect, except pouring the wrong powder in the powder measure. I type this slowly with my left hand, embarrassed but … possibly saving someone else a tragedy or, like me, a long drive to the Emergency Room and surgery to save my finger.”

CLICK HERE for bigger, more graphic photo of injury.
Varget Kaboom TiteGroup Hand injury reloading fingers accident

The Still-Sealed Bottle of Varget
Denny did not initially comprehend exactly why the kaboom happened. He thought maybe his new Savage rifle was at fault. Then, on his return home, he discovered something…

Denny wrote: “The seven-hour period it took to go to ER, transport to Trauma Center and surgery made me think it was a Savage rifle issue. Brand new rifle, new brass, triple-checked loading data. The next day I was humbled when I realized the Varget powder was still sealed.

I knew what powder to use. I thought [Varget] was what I used. Not until the following day did I realize the Varget was still sealed.”

At that point, Denny realized what caused the accident — “operator error”. He knew he had to warn others about using the wrong powder: “I knew I needed to share my mistake, even though it is embarrassing, just to remind people. I’ve been reloading for 30 years…”

Editor’s Comment: Denny was not a novice reloader. His experience demonstrates that this kind of mistake can be made by any hand-loader, even one with decades of experience. Be safe guys, take your time when you load your ammo. Remove powders from measures after your loading sessions (pistol powders can look very similar to rifle powders). And by all means CHECK the LABEL on the jug. As the TiteGroup label says: “A little goes a long way.”

It’s not a bad idea to separate your pistol powders from your rifle powders, or perhaps even load for pistol in a separate part of your workshop.

USAMU Advice for Progressive Press Users

Accurateshooter.com USAMU progressive press reloading

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.

USAMU Reloading

Progressive Press Safety Considerations by USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.

Worse yet, several different handloading operations would be occurring at different stations on the progressive press at the same time. It takes an experienced operator to keep track of, and truly understand the significance of, all those potential mini-problems. Loading without this experience is a recipe for potential disaster – such as a double powder charge (especially with pistol cartridges) dropped while the loader was attending to some other function, etc. Progressives are an animal unto themselves, and while they offer many benefits, they do take some getting used to – even by experienced handloaders!

ILLUSTRATIVE HORROR STORY
Here, enter a 40-year veteran handloader who decided to jump onto the progressive bandwagon late in his career, having used only single-stage presses all his life. A High Master NRA High Power Rifle competitor, he had no background in competitive pistol shooting, where historically most progressive presses are found.

Experienced Action Pistol shooters have typically encountered multiple episodes in which shooters “skipped” a powder charge for some reason, leading to a squib round and a bullet possibly lodged in the bore. Thus, at matches, it’s reflexive for them to yell “STOP!” in unison if they see a shooter get a “click” vs. a “bang”, and rack the slide to keep firing. This writer has personally seen several pistols saved in just such scenarios over the years.

Click No Bang — What NOT to Do
Our High Master set up a popular progressive press and began turning out .223 Rem 100-yard practice ammo with abandon. He was using a moly-coated 52gr match bullet and an economical, fast-burning surplus powder that gave great accuracy. Once on the range, he began practicing strings of rapid-fire. All was well, until he heard “Click!” rather than “Boom”.

Lacking the above experience or onlookers to halt him, he reflexively operated the charging handle on his expensive, custom NM AR15 Service Rifle, and the next trigger squeeze reportedly registered on seismographs over at least a three-state radius. He sat, uninjured but bewildered, until the hail of expensive bits and pieces quit raining down around him.

When the smoke cleared, he immediately cursed the horrid, evil, demonically-possessed progressive press for this, his first-ever reloading mishap. His $1400 NM upper was ruined, but thankfully, his $800 pre-ban lower… and he had escaped injury.

This tale is told not to discourage the use of progressive presses, but to emphasize the need to EASILY and IMMEDIATELY KNOW what is happening with the press at each station, every time the handle is cranked. Not to do so is, as they say, “bad ju-ju.”

It illustrates why we at the USAMU Handloading Shop agree in recommending that new handloaders should begin with a single-stage press. Once one thoroughly learns the steps in each phase of handloading by repeated experience, then one will be qualified to move on to a progressive press.

The single-stage press will REMAIN virtually indispensable for one’s entire handloading career, even after having purchased a progressive press (or two). There are endless small projects that are best handled on a single-stage press, and a poll of USAMU’s Handloading staff reveals that not one would willingly be without his single-stage press, despite owning at least one progressive.

Don’t Ruin Your Hunt — And Your Rifle — With Ammo Mistake

223 WSSM 6BR blow-up

hunting safety kaboom rifle cartridgeHunting season is right around the corner. For many of us, that means liberating a rifle that sits in a safe most of the year, grabbing a box of cartridges, and heading to the wilds. But this “once a year thing” carries with it potential risks.

It is all to easy to grab some rounds that may look right, but which are, in fact, a slightly different chambering. Likewise it is possible some hunting rounds got put in the wrong box after last year’s hunting trip. Be very careful when you get ready for a hunting trip — check the headstamp, cartridge dimensions, and bullet diameter of all your rounds. If you make an ammo selection mistake, the consequences can be disasterous, as this story reveals.

The .223 WSSM and 6mmBR Disaster
Report by Dr. Jim Clary
Under most circumstances, shooters don’t have to worry about chambering the wrong cartridge into the wrong rifle. After all, the cartridges are well marked and we all know which rifle we are shooting on any given day. In many cases, incorrect cartridges cannot be chambered — larger cases will not fit in smaller chambers, for example. No problem! That being said, I can tell you that even an experienced, careful and normally safe shooter can make a mistake.

The following is an account of just such a mistake that could have resulted in death or dismemberment. Fortunately, the shooter was not hurt, but the rifle was completely destroyed.

Last year, a friend purchased a Savage Precision right bolt, left port, single shot bolt action in 6mmBR Norma. It was an incredible prairie dog gun and he spent the summer burning powder and busting dogs. In October, he purchased a stainless steel Browning A-Bolt Varmint in .223 WSSM. The weather in the upper Midwest turned sour by the time he got the brass tuned up and he only got to fire it a few times before he was “socked in” for the winter. Thus, he spent his evenings loading ammo for the spring thaw.

During a break in the weather, he grabbed both rifles and a couple of bags of .223 WSSM and 6mmBR cartridges and headed to the range to check out his new loads. In case you are not familiar, the 6mmBR is smaller in diameter and a mite shorter than the .223 WSSM. Because of this, it will chamber in a .223 WSSM, but the .243 caliber (6mm) bullet is too big for the .22 caliber bore. That is what happened to my friend.

The rest is history — when he squeezed the trigger, all hell broke loose. The entire bottom of the rifle blew out, including the magazine assembly. The explosion actually cut the stock into two pieces. However, the bolt held and amazing as it may seem, the .243 bullet was “swaged” right out of the .223 barrel.

223 WSSM 6BR blow-up

One Small Mistake Is All It Takes
Now, realize that my friend has been shooting all manner of firearms, safely, for over half a century. He is meticulous, thorough and conscientious in his approach to reloading and shooting. However, he made one mistake. He put some lose 6BR cartridges in a baggie as he packed up from a prairie dog hunt last summer, without noticing that the baggie was marked .223 WSSM in black marker. Then, when the break in his winter weather came, he grabbed the bag, believing it to be the WSSM cartridges and didn’t check the head stamp.

Couldn’t happen to you? How many times have we emptied our pockets of cartridges and dropped them into a plastic container on the shooting bench? How many times have we set down to a marathon reloading session, loading several calibers in a row? How many times have we put the wrong bullets, cases or primers into the incorrect container? My point is that even the safest of us can make a mistake. So, look at the picture above and take a bit more time when you reload your ammunition at home or chamber a round in the field. It might save your life.

Black Rifle Blow-Ups — The Kaboom Collection

AR15 AR-15 Kaboom explosion pistol powder accident catastrophic destroyed

This shocking photo of destroyed AR-15 bits and pieces was posted on Facebook by William Walter, a firearms instructor. William said this was “The worst AR-15 blow-up I have ever seen. The case head literally atomized …you can see the brass residue on the parts. The bolt was split in two also.”

There’s nothing inherently wrong with AR-platform rifles (well, except that they run dirty). Over the past six decades Eugene Stoner’s semi-automatic design has proven its merits in military and civilian applications. You may not know, but the original AR from 1955 was a .30-caliber. The Armalite AR-10 shot the 7.62×51 cartridge. Later, at the request of the U.S. Military, Armalite created a smaller version that became the M16/AR15. The rest was history. Now there are millions of AR “black rifles” in the hands of soldiers and sportsmen.

With so many ARs in circulation, it’s no surprise that some get used by folks who don’t know how to hand-load or otherwise fail to follow safe gun practices. The AR is actually a pretty sturdy rifle, but when it’s fed bad ammo, or abused, bad things can happen. Very bad things… commonly known as Kabooms.

The American Shooting Journal (ASJ) has compiled a set of particularly extreme AR Kabooms. Compiling the “evidence” from various web sites, ASJ has published nine (9) of the most Unbelievable AR-15 Fails. Here are two of the worst “AR-15 Fails”. CLICK HERE to see them all.

Nothing but busted parts after this catastrophic Kaboom…

These catastrophic AR failures are eye-openers, that’s for sure. ASJ cautions: “Any weapon can fail if given the wrong ammunition, faulty reloads or a plugged barrel. Always be aware of what can happen at anytime if you fail to follow common sense and gun safety rules.”

Your Worst Nightmare: Catastrophic .338 Lapua Magnum Kaboom

Click to zoom image

We first ran this story a couple years back. We’re republishing it today as a reminder to our readers that safety should be their paramount concern at the range. Avoid distractions and always check your barrel for obstructions before you chamber a round or pull the trigger. A moment of inattention can result in a catastrophic kaboom …

Discharging a .338 Lapua Magnum round with a cleaning rod in the barrel — that’s a recipe for disaster. What happens when a fired .338 caliber bullet and a cleaning rod try to occupy the same place at the same time? Well you get a catastrophic kaboom, with metal pieces flying all over the place, and a shooter very lucky to escape without serious injury. This incident occurred recently in Manatee, Florida, as reported by Sniper’s Hide member Queequeg. We thank SnipersHide.com for granting permission to publish these revealing images in the Daily Bulletin. CLICK HERE for more Kaboom info on the ‘Hide.

This story should serve as a chilling reminder to follow proper safety practices whenever you are at the range. Always check to make sure there is no obstruction in the bore BEFORE loading a live round.

.338 Lapua Magnum + Cleaning Rod + Inattention = Kaboom!

Kaboom at Manatee!
Sniper’s Hide member Queequeg recently published shocking photos of a catastrophic kaboom involving a .338 Lapua Magnum (Savage action). The action was blown off the rifle, shrapnel went through the roof, and the barrel split at the tenon before taking an excursion downrange. The action did crack in the front but the lugs remained engaged so the bolt did not slam to the rear (luckily for the shooter).

Here’s the report: “This happened [January 20, 2014] at the Manatee Gun and Archery Club. Al, Ren and myself were there with a couple other folks. Ren was at bench 12, I was at 13. The fellow at 11 was running a Savage .338 Lapua. He had a very bad day! He damn sure could have killed himself and quite likely Ren as well.”

Queeqeg added: “After the boom, I heard Ren ask ‘Are you alright’ and then turned to look in time to see the fellow reacting in total shock — literally stunned. Ren and I went over to him and could not see any major injuries. Ren was uninjured as well but had a lot of fiberglass splinters on him. The barrel nut is what I presume punched the two holes in the roof. The shooter is a regular there[.] He had been having a problem with sticky cases though he said he was certain the loads were mild. That’s why he was content to knock the sticky ones out with the rod. He simply forgot to remove the rod after knocking out the last stuck case. You can see what happened next.”

The Important Lesson Here
What did the .338 LM shooter do wrong here? You will say — “Well that’s obvious, he left a cleaning rod in the barrel and then shot a round.” Yes, that was a potentially fatal error. But that was his second mistake — one that occurred only because he made a more fundamental judgment error first.

The FIRST mistake was not acknowledging the problem with his ammo. Had he heeded the warning signs, he would still have a rifle (and an unsoiled pair of trousers). When he first observed that he was having problems with extracting cases, a warning light should have gone off in his head. Presuming his extractor was not broken (and that the chamber was cut properly) he should have been able to extract his brass if he was running safe loads. The lesson here we all need to learn is that if you observe a serious ammo-related issue, it is time to stop shooting. Don’t try to invent work-arounds just to extend your range session, when there are clear signs that something is wrong, very wrong.
