9mm case explosion with Gen 3 G34

I'm glad you're okay platoonDaddy! Scary sh!t for sure!

I got that beat!

Double Load(checked that box)?

Catastrophic failure: I was at the range this morning and this happened. I had experienced a squib round(no powder) where the primer pushed the 9mm bullet into the rifling. Hearing just a puff sound, I knew to stop, wait, drop the mag and eject the expected empty case. I made the gun safe and...

In all seriousness, glad both of you are ok and can share your tales as a sobering yet not tragic reminder to be safe.

I'm glad you guys are ok too.

Maybe we need to do a safety stand down on our Glock-types and reloads??

Unsupported chamber. Brass casing exploded because of it.

This AM shooting my WIN brass reloads; 5.5 Grs of WSF, COL 1.169, CCI #500, had an explosion. Note attached pictures. Of course it resulted in a few minor burns to both hands. I don’t keep count of the # of times the brass was reloaded. During reloading, every so many rounds I will check a few with a Wilson Pistol Gage.

Any idea on what might have caused the issue..

I was thinking of visiting you guys this morning. Always a day late and a dollar short. Glad you're OK old man.

I've had something similar happen to me in the past and in my instance, I believe the slide was not all the way forward (or in battery). I suspect it was caused by me not properly resizing a brass cartridge on the Dillon (short stroke) and the slide of the pistol not fully closing when it went bang. Most of the brass I reload is range pickups (aka junk).

I check every round I fire in an ammo checker block and probably 11-12K rounds later, I've not had a problem (but I discard/disassemble my reload rejects - still have those from time to time).

Get a KKM barrel. It won't scare you and it will be more accurate.

Was using Wilson Combat Barrel

Thanks!

Forgot to add: on Tuesday Joe is going to explain the eclipse..

Ok, then your disconnector is allowing the striker to release when the slide is not in battery.

Unsupported Glock chamber perhaps?

Unsupported chamber , Plus brass ( the metal ) that was out if spec soft , or too thin .

I have over 1.5K rounds down range on this barrel without an issue….

That's why I suggested testing how much out of battery was necessary to stop the firing pin.

That's a good point.

Sorry, didn't catch that. Excellent idea. I have found some that will allow ignition with the case halfway out of the chamber.

Well, until you get an out of spec round or a chamber dirty enough to keep the case from fully chambering, you won't see a problem. That is why it is a good idea to check periodically by holding the slide away from full lockup and see where it disconnects.

 

[outrider58]

Differences in case webs can be a concern too, in this case.

(no pun intended)

 

[El_flasko]

I saw the case in person today. Unreal.

If it were firing out of battery, the primer strike would be off center. That looks typically centered. Not out of battery.

Honestly, it looks like a bad piece of brass.

What makes you say that? If the chamber is in spec, and the majority of the case is in the chamber, the firing pin is going to strike the center of the primer.
