Primer blow out

[hardhead]

I was at Front Sight over the weekend and saw a guy shooting S&B 45 out of a 1911. The primer completely blew out leaving an empty but sooty flash hole. The bullet didn't budge and it was a major pain to eject the cartridge. After racking the slide about 15 times, it finally popped out. Wish I would have thought to take a picture of it. Any idea what might have caused that? The guy was complaining about either extractor or ejector issues afterwards. He started getting type 2 malfunctions.

Type 2 malfunction?

I have heard of Type 2 Diabetes, but not a Type 2 malfunction...

Hmm, maybe damaged primer or maybe something was partly blocking the primer so it was not seated all of the way and when it shot, it popped out. (Gotta protect your flashhole...)

Was the primer hole plugged up too?

I know that if you put a primer in a shell and just fire it off the primer will jump out of the shell a bit, could have been defective brass too that was a bit loose on the pocket.

Surely you jest...

Brass high, stove pipe, smoke stack, etc.

I didn't thoroughly inspect it. I saw that the primer was gone and there was evidence of detonation, but the bullet was fully seated and everything else appeared normal. Very bizarre.

So your saying the crack staff at front Sight have never heard of a "squib rod" and didn't have one on hand for just such an event. Instead they advocated racking the slide over and over possibly damaging the extractor?

They should put that in their sales brochure.

Actually after rereading your post it appears he did damage the extractor.

IMO, the blown primer is probably due to a double charge or hot load. that hot load in turn, damaged the extractor because the case is stuck in the chamber and cranking on the slide multiple times puts a lot of strain on that extractor.

Good thing Front Sight only allows factory ammo in their courses. That way things like this can never happen. Don't want any of those dangerous reloader types on the firing line.

Sounds like the ejected case still had the bullet in it? Maybe no flash hole in the case so the primer just blew itself out of the primer pocket??

Wait, the bullet remained in the case?...

Can a primer ignite if struck backwards(i would think so...)? Maybe a backwards seated primer that didn't get caught? It would ram the cartridge in there pretty well and would think leave the bullet in the case?...
I don't know, sounds plausible after 30 seconds careful consideration.....

Yes, the bullet remained in the case and the cartridge looked perfectly normal other than the primer had detonated. Maybe it was in there backwards or maybe the flash hole wasn't cut out completely.

I had a RWS case without a flashhole and it jammed up my bolt so good I had to send it in.

It sounds like it was most likely a missing or obstructed flashhole. If you seat a primer upside down, it usually does nothing. It sounds like the powder did not ignite since the bullet didn't move so I don't think it was the load. But, who knows without seeing it.

[Twystd1]

I agree. Sounds like an obstructed flash hole. I fixed a jammed M&P last night with the same problem. That sucker was locked up tight.

After ten minutes with a block of wood and a soft blow hammer. We cleared the round.

Fun stuff.

Impossible.

The bullet would have shot backwards and possibly hit him...

S#*t stilly, you don't think its the dark matter testing all over again do you? I mean, they never said they found/located the primer...

Certain tumbling media will perfectly block a flash hole.
