    its on the line, NOVA

    Raise your hand if you've ever experienced a kaBoom.

    ...during an Aim Fast Hit Fast class

    ...during a solo F.A.S.T. run.

    All of your hands should be down. Mine is not, sadly.

    It has taken me awhile to write this, mostly due to the mental trauma sustained in this incident. This is part of my healing.

    It was during my 3rd FAST run of the class, on Sunday morning. After getting on The Wall the day before, on this run I proceeded to badly miss both headshots, reload, and blow my gun up on the first body shot.

    It happened very fast, obviously. I remember dropping the gun; Todd says it was more of a touchdown spike. I remember looking at my now black hands from the partially burnt powder, and seeing and feeling all my fingers. That part felt nice.

    Then the realization set in of exactly what happened. I just blew up my gun.

    TLG was awesome. Not only did he not tell me to GTFO of class, he secured the gun and spent about 10 or so minutes un-jamming it to see the full extent of the damage. It was locked up extremely tight, and freeing the slide involved viciously pounding it on a wood block to get it back far enough to get the safety plunger out.



    So how did this happen? The TLG version of the story is that after seeing the headshots miss, I purposely grabbed a magazine that contained a 9mm bomb of my own deliberate manufacture, in order to use my one allowed reshoot due to "extreme equipment malfunction". While very hilarious, it isn't true.

    The most likely answer is that I simply screwed up. Screwed up fantastically. A textbook double charge is my current assumption. But I am open to other possibilities, particularly ones that don't make me appear so bumpkin-ish.
    At that time (SEPT 2011) I had been reloading for around 8 or 9 months, and had reloaded about 7k trouble-free rounds. Like most accidents firearm-wise, it only takes one.


    Damage

    As you'll see in the pictures, damage is actually not that bad. Nothing appears to be permanent.

    The extractor was lost. We never found it. I imagine its still in orbit. Or perhaps some of it is.

    The White Sound HRED I had installed (aftermarket spring loaded extractor bearing) was half-destroyed. I have the big rod, but the spring and the small part that contacts the extractor were lost. I imagine they are wherever the extractor is.

    Half the casing was sealed in the chamber. Apparently this is not difficult to remove.

    The magazine shot out of the gun, and was destroyed. The magazine catch seems to be fine.

    And of course my pride was grievously injured.

    As bad as it was, it really could have been much worse.
    My Glock is currently back home at Glock INC in Georgia, being inspected for damage by the pros at the factory. If its ok, it will get a new extractor, the new ejector, and the latest recoil spring assembly.
    I can't wait to get it back. I have been shooting a couple of my gen3 Glocks since, and its shown me how much I really dig the GEN4 frame.

    I still reload. I recently passed the 13k mark on my 550b. But I'm alot more careful, and I don't reload as much at one time. I actually have an idea of how I could have done this. It involves me loading for a long period, becoming fatigued and letting myself get distracted.

    And now, pictures of the carnage. I fear you'll be a little disappointed.





    the casing sealed in the chamber




    The other half of the casing. The deformity is pretty amazing. I can't even read the headstamp, as it is totally flat. The pressure apparently literally flattened out the headstamp. Awesome.




    more of the case








    the magazine. as mentioned, its toast.










    here the "track" the magazine catch cut through the magazine can be seen.




    my Gen4 17, before it got sent back to Glock.

    Fuse,

    Glad you walked away with all your physical parts. Also great to see that this did not stop you from reloading, this would have been an easy time to stop. Not sure what your standard load or powder is, but I purposely pick a powder that is bulky and has a relatively slow burn, just in case I screw up. My powder of choice for 9mm and .40 is Unique made by Alliant. I have found that this powder is bulky and fluffy enough to leave just enough room for bullet seating, while maintaining safe pressure and velocity. In the event of a double charge, it overflows the case and gives me a visual warning while I set the bullet in the case mouth. And you asked for other possibilities.... (1)If you are using brass of unknown origin and unknown times fired, the case may have been catastrophically weakened before you loaded it. It may have been bulged past its elasticity and re sized without your knowledge. (2) It could have been once fired brass and got damaged while on the ground (pressed onto a rock, making a weak spot), that might have been enough if your loads run on the higher pressure side. (3)And yet another possibility is that some tumbling media or other foreign substance remained in the case; this would take up case volume and cause a pressure spike......

    Again just some possibilities. But glad your are ok and that the situation was handled well.

    Wow bro, no bueno! Good to see you've still got your phalanges and whatnot.

    As to quality control, what is commonly done by reloaders to ensure things like this don't happen?

    What else can be done?

    While I was not the shooter...about 10 years ago I was at teh range with my grandpa and he was shooting his AMT .45 win mag, I'm not sure if it was a double charge or a round followed by a squib but the gun exploded...sending part of the slide through the ceiling of the shooting range and causing the barrel to peel back...I was only 13 at the time but I remember having a holy sh!t look on my face, luckily no one was hurt.

    The whole "don't multitask and be distracted" thing isn't very solid given we're humans and make mistakes. That's not a QC measure in my opinion....AFAIK, QC are processes to check that we did the job right.

    Would visually inspect every cartridge include weighing the product? If it was double-charged, you'd be able to tell by weighing, right? I imagine it'd be pretty time consuming to weigh every cartridge, but maybe weigh 500 at a time. There's the small chance that one could be overloaded and one underloaded, leveling out the total weight, but I think it'd be a better compromise than just saying, "nah, I did it right" and going about the day.

    Or does this powder check pretty much take care of the issue?

    I only ever reloaded shotgun shells when I was a kid, about 30 to 50 at a time. Never reloaded handgun or rifle ammo, and have never reloaded in bulk.

    The point is, you'll make more mistakes if you allow yourself to be distracted. Don't watch TV, don't surf the web, don't do things which force you to pay LESS attention to the task at hand.

    No, visual is just that - visual. I'm not going to weigh each round that I reload for pistol. You should be able to see a double charge, and if you pick the powder correctly, you won't be able to seat a bullet. It's easy to look in the charged case before you seat a bullet.

    I do weigh each charge that I reload for precision rifle, but I don't weigh the loaded round.

    The dillon system checks for gross charge errors, like a 0 or 2x charge.

    Dude glad you're OK.

    25 years plus of reloading I never had an issue UNTIL, my Dillon powder measure started sticking in the delivered position. I would constantly clean it, check for burrs, stuck powder etc. I never called Dillon and asked about a replacement.

    At my first outdoor IDPA match I had perfect storm of errors that led to a bulged barrel, broken ejector and bruised pride. First my electronic ear pro failed mid match. It wasn't a battery problem, they just quit working. Now after 3 decades of shooting and working around loud truck motors my hearing is less than perfect. So midway thru the last stage of the day I had a squib round that just the primer went off, there was no powder since the powder measure had stuck in the open position and I missed it. Since my ear pro failed and I can't hear worth damn without them I thought it was a dud. Tap Rack BANG! It seemed that the squib round pushed the bullet only half way down the barrel. The follow up shot cleared the stuck round and caused the barrel to swell enough that the slide locked half way back and was stuck on bulge. Good news was the result was 2 down zero shots. Bad news was that it took a rubber mallet to free the slide and a new barrel and ejector to fix the gun. Thank god I was shooting CDP and the 45 is a lower pressure round. Add to that the S&W 645 is built like a tank. Only injury was my pride.

    Lesson learned. I immediately contacted Dillon and they sent me a new powder measure at no cost. They really mean lifetime no BS warranty, no arguments no lengthy discussions. Secondly I limit myself to loading 200 to 300 rounds at a time. If I get tired or distracted I stop. Each and every case I look into and make sure there is powder in it and that it looks like the right amount. If I think I missed checking a round I pull the bullet and make sure there is powder or throw it in the permanently rejected box for proper disposal. Also I had new ear pros the next time I was at the range.

    The match director was an extremely good guy and took pity on me. He scored the 4 shots I didn't shoot as misses and did not give me any FTN's. That allowed me to finish forth in the division. I should have gotten a DNF.

    The variance in bullet and case weight (especially if like me you use mixed cases for most ammo) is enough that weighing single rounds wouldnt tell you much reliabily. Weighing 500 at a time would tell you nothing.

    The plated bullets I use have a grain or two variance in weight. The cases even more. The 4.5 grains of powder can easily be confused.
