Herp Derp Kaboom

I’m sure we’ve all seen gun kabooms online before and usually the involve the shooter doing something, shall we say, less than intelligent. More times than not kabooms are directly related to improperly reloaded ammunition or bullet setback caused by chambering the same round too many times. This kaboom hs a result of doing something, getting a bad result, and doing it again:

When DoubleTap started offering ammo for it, I bought a bunch of their ammo loaded with 165 grain Gold Dot bullets. It was supposed to be the ultimate 10mm self defense round.

But I noticed some of the brass looked like this:

Below that is a picture of a 10mm brass casing with a huge fucking bulge in the back. From there the poster did a smart thing, followed by a not so smart thing:

I called Glock, and they asked that I send the gun in for inspection. I asked if I could just send in the barrel, and they said no. The whole gun. Screw that. I’ll just use the KKM barrel.

Noticing the failure and contacting the manufacturer was a very smart move. Not sending the gun in upon request wasn’t so smart. At least the poster replaced the barrel which appeared to be the source of the case bulges. It’s not like he would be stupid enough to use the old barrel anyways… fuck:

So I went to the range this morning.

With the original barrel in the pistol, I used calipers to measure the overall length of a round. I loaded it into the magazine and then put another round on top. I chambered the round that was on top and fired it into the berm. I then ejected the first round and remeasured the overall length. Identical to what it was.

And there was no bulge on the fired DoubleTap brass.

Thinking it might take a few rounds to cause bullet setback, I loaded the first round again, and then two others. Chambered the round, and fired into the berm. KaBoom.


That’s strange whenever I fire this firearm the ejected brass always have a huge bulge in the back of the case. What should I do? I know! I’ll keep firing this gun in this configuration with this ammunition!

Seriously people don’t be this guy. If your noticing potentially dangerous issues with your firearm do not continue to fire it. Diagnose the issue and correct it or have somebody qualified diagnose and correct the issue. Remember that firearms are basically devices that harness controlled explosions in metal tubes and thus a failure has the potentially to be incredibly dangerous.

The poster was lucky that he didn’t get seriously hurt and I really hope he learned a lesson from this.
