found at the range

looks like someone was trying to push 9mm.
glad he left before i got there.

 

[Kamicosmos]

wow!

brass is in otherwise fair shape. perhaps it was Clarke?

 

[happy old sailor]

gasp

Sorry....what does that mean? Somebody was using 9mm Luger in a gun chambered for something else?

Or was it reloaded improperly?

 

[The Bushmaster]

Man...Clark sure do catch hell these days...You would say they were a bit hot???

 

[R.H. Lee]

When primers blow and crater like that it's an indication of very high pressure.

 

[blboyd]

So ya'll are trying to say that you're brass isn't suppose to look like that? Maybe that's what I'm doing wrong... Jus' Kiddin'

I guess somebody doesn't inspect thier handloads.

I don't know about respecting their handloads, but they sure don't respect their hands and eyes...

 

[Murphster]

We should save this thread for the next time somebody asks if they should buy and shoot reloads they found for a good price at a gun show.

+1 to that.....

If that ain't over pressure rounds, my name is Genghis Khan!

Funny how we ask for Clark!!

 

[bigjim]

Glock brass.

 

[redneck2]

Glock brass.

Shows how much you know. Glocks always blow out the sides, not out the back

Oh wait....I've got a G20 and it's never blown the brass. Maybe I forgot to load it as hot as the brass in the picture. Better ramp it up

 

[RecoilRob]

I looked closely at the pics and am not sure that overpressure is really the culprit here. How do the cases measure? If the bases are not expanded badly, which (by the pics anyhow) they don't appear to be, they might be OK.

Having ruined my share of 9MM brass with overpressure, these don't look anything like the buldged horrors I have made in the past.

Could this not be caused by a firing pin being too sharp and piercing the primer? And, this would allow the primer to flow excessively into the FP hole which appears to have happened on several cases.

Also, look at the edges of the primers....still rounded. Almost no flattening at all. My overpressure experiences have had the primers flowed out sharp to the edge of the pocket and never blew one out. Just wondering.....

 

[The Bushmaster]

As much as I dislike plastic guns (they seem to have the most failures), you may be on the right track. RecoilRob. Although my last experience with a failure of the factory to finish the firing pin on a SAA Colt tended to punch all of the primers. May have been because of the longer hammer fall. The cases, upon closer inspection, only have two of the six signs that I look for in a hot load. Punched primers and primer flow back. The other four that seem to be missing are; balooned cases, flattened primers, split case mid way down and hard to eject. I don't see any signs of pulled rims here. Cases look to be partially expanded, but not bad...

I don't want to have the whole rath of the glock lovers down on me here, but knowing that glocks tend to double tap the primer upon firing, could this be a slightly extended firing pin or a stuck one??? (improperly cleaned firearm)

Standby....Incoming!!!

 

[bigjim]

No bushmaster that is not Glock brass, they don't have that stupid abandoned by GOD square firing pin strike. Also they don't have the fish belly
no chamber support Glock brass modification.

No this shooter was trying to destroy some other gun. Since it was not a Glock they were not able to get it done.

Sorry about this post I have been reading the DU forum and my style has evolved.

L M A O. BigJim...Needed that this morning...

 

[fecmech]

No disrespect to any of the previous posters but I'm with Recoil Rob on this one. I don't think those are overpressure loads, more like a firing pin problem or something else gun related. The primers are not flattened, the edges show no blackening and from the pics I don't see any bulging of the brass. Nick

 

[Rockstar]

How about some links to evidence that Glocks "double tap?" I've heard a lot of airheaded b.s., but that's right up there with the best of 'em.

BTW, looks like "pointy f.p. syndrome" to me.

 

[The Bushmaster]

My, my Rockstar...You sure are a nice guy...Calm down...Geezzz

So I miss worded the square pin (what BigJim said) mark that (thank God know one else uses) as a double tap of the firing pin...Damned sorry....

 

[shu]

hes, i believe i'll revise my original estimate. do not have much experience looking at overpressured brass (have been known to stoke 357mag, 357sig, and 9mm to published limits, but have never knowingly gone beyond).

however it is my understanding that with overpressure the primers would flatten against the breachface and fill in the valley between primer pocket and primer. these show no sign of that.

they do however show primer flowing back into the firing pin hole in the breach.

in any event, if primer were holed by the firing pin would not that vent gasses into the magazine (an event with few if any benevelent results)?

 

[TooTaxed]

While inspecting before priming a batch of .45 Auto brass picked up at the Ft. Benning Rifle & Pistol Club over time, I recently found several Winchester brass with vastly oversized primer flash holes. These were probably intentionally drilled out to fire parafin or rubber bullets with primer power only...but what were they doing at a range? Glad I did not load them with my normal loads...!

 

[rbernie]

That was my first thought when I saw the pics - this is probably not an overpressure sign since the primers are still well formed at their circumference and are not flattened in any way. I suspect a firing pin protrusion issue.

 

[dxkj21]

The firing pin might do that if you stuck a 9x19 shell in a 9x18 gun?

 

[Red_SC]

TooTaxed, are you sure they weren't from some of the older WinClean ammo? I have some brass with much bigger flash holes from that. I reload and fire it like normal, never thought much about it. I hate that Winclean ammo, though.
