I was wondering where that case went! It ejected so hard here on the range in the USA we never found it. Glad you did.

Have seen flattened primers before but never like that one.  Primer metal almost looks crystalline, wonder was it really a hot load or is the primer material defective in some way.  Any idea if that was a reload or a factory round.  Would be interesting to measure case head for expansion.

I've done this type of flattened primer several times in my younger days before commnon sense reloading set in. I had a scoped Ruger Blackhawk .30 Carbine that I was trying to make into a ground squirrel gun using 93 grain Norma softpoints. Blue Dot and Herco powder gave some high velocities and spectacular results when I connectedd with a ground squirrel. 

The depriming effort was a hard push to start and then the primer judt fell out. Often, the primer pocket was swelled enough the new primer would not stick in the case. These were miiltary cases, the W-W cases were thinner and did not develop quite the pressure.

Fortunartely, common sense struck and I backed off the loadings.

The pattern may be the reverse of the surface of the bolt face. 
Amazing it did not rupture!
Case head expansion is probably excessive but you don't have the original diameter.
You can base it on cartridge specs, but that is not sure. 

Is that extractor damage at the top?

"Is that extractor damage at the top?" - That is probably the brass flowing into the extractor cut.

I was working a helicopter gunnery range years ago.A mini gun on one of the Cobras was malfunctioning.I picked up some brass after a testfire.No flattened primers.There was no primer at all.The primer pocket was at least 5/16 of an inch.One of the barrels had a ruptured case and was still chambering and firing a round.Must have some high pressure.The gun was undamaged.

Here is a 308 Win that got fired in a Ruger M77 .270 Win. The rifle survived. We had to beat the bolt out with a #2 sledge. Imagine my surprise when I saw the "308" cartridge ID in a .270 Rifle. This is from my "Stupid Shooter" collection I have acquired with 50 years on a firing line as an Instructor and a R,O. The collection is staggering and the personal injuries I have seen are amazing. Fortunately no deaths but a few came very close to bleeding to death.

You think this only happens to stupid people, until it happens to you. Being over confident and not double checking is ONE of the causes. Lot more reasons way this happens.

Yep, like cross firing during a match. There are those that have and those that eventually will. Got be very careful to prevent those double charges. Those that shoot subsonic get particularly sensitive when loading pistol powders in a rifle case. As you get older you start to build in practices that make it as idiot proof as possible. Bill C

Yes true education is never cheap. One of my early “lessons” was the paper drum of 12,000 military once fired .308 cases. Reloaded 1,000 of them after painstakingly prepping the cases. Went to the range and was firing them in an FN-FAL. After the first magazine I noticed that most of the spent cases were in two pieces on the ground. Those that weren’t had partial head separations. Learned that .308s fired in M60 machine guns with excessive headspace should not be reloaded. When probed the cases all had incipient head separations. Also bought my first collet bullet puller after learning inertia types were meant for a round or two, not 950+. Amazingly no gas leaked and no damage to the rifle. Had my first experience in the scrap metal market too. Remember it’s “cartridge brass” and worth a little more.

I happened across one of our clubs range officers who was having trouble with his new 6.5 greedmore.

It was failing to fire.

 I looked at his empties and found a hole the size of the firing pin going though the primer.

you could blow through the hole.

‘I pointed it out to him and said it was probably just a build up of brass on his pin stopping it moving forward enough.

I said I  thought that his loads were a might too hot.

Ha he said , must of used 2207 instead of 2208 and just kept on shooting.

And they call me a far. King idjot

Years ago I've picked up a couple 9's or 45's (don't recall which) with base blown out through the feed ramp. Nope not mine.

i got lucky and blew up a rifle when i was 12 years old ...  a strong marlin 81 bolt 22rf ... not my fault, had usa ammo ... but case let go and blew off extractor and split the walnut stock ... i reasoned that if 2 grains of powder in a 22rf could do that, maybe i should be careful with 60 grains in a 30-06 ...  i dipstick each and every load since ... haven't found doubles but have found empties ...What Thu !! ...

.50 Cal primer grown up in a friend's cheek and gum

An older friend of mine, who was in WWII had an unusual happening. They were sweeping an island getting all of the remaining Japanese soldiers out. The Japanese were hidden in what was called spider holes by the US troops. Spider holes were little holes dug in the ground with camo tops over them and un-expectedly the Japanese soldiers would raise up and open fire. During this operation my friend was stabbed completely through his face, in one cheek and out the other, by a Japanese bayonet. He had the 7,7 Japanese rifle and bayonet that stabbed him mounted over the mantle of his fireplace. He continued through the sweeping operation before receiving medical attention.

In the early nineties he was having some dental problems. The dentist was removing a stubborn molar, having to do a little cutting, when he discovered something grown up in his cheek and gum. He removed it and guess what it was, a 50 cal primer. Evidently a 50 cal had blown a primer and it just happened to go in the open stab wound in his face. He made a little walnut plaque and mounted the primer on it and placed that on his mantle to go along with his trophy rifle. If anyone who thinks these people weren't a different breed of cat, they have another think coming. Danny Daniels died in the early 2012. I lost a good friend and the world lost a great man.I may be goofed up on this being a primer from a 50 cal, i would think on this type of operation you would be more likely to be in the vicinity of a BAR than a 50.I can't remember exactly what he said,SORRY.

My brother-in-law and I ordered 2,000 precleaned and de-primed .223 cases from Midway years ago While loading mine I had a case separation when witthdrawing the case from a sizing die. We loaded a bunch of these and took them on a prairie dog shoot. We were firing these through two different rifles and the cases were sized to fit each individual rifle. 99% of these had a case separation when fired. good thing we had plenty of good ammunition and lots of rifles in different calibers. The only thing that I could figure out was that they had all been fired though a fully auto rifle and the case wasn't getting fully seated before ignition.

I've never seen a 666 headstamp. At work we have Tank 665 and Tank 667 but no Tank 666. Seemed that there was enough pressure from employees of the Christian faith that we had to remove the number from the tank and renumber all the following tanks in that group.

Maybe not a good idea to use brass with that number?

The headstamp is GGG.

After I posted, I looked closer and it did seem like G's not 6's. At the range I picked up a short skinny bullet cartridge and it appeared to be a RP B 78. After closer inspection and some removal of corrosion, it turned out to be a B 18 6.5 Carcano from the Bologna Arsenal in 1918 with the inspectors stamp BP. Cool find in the unfired ammo bucket. Usually its just 22 LR and 30-30 plus the odd bad handload!
