30-06 brass (Doh!!!)

[kestak]

Greetings,

Please look at that picture. I picked up that brass into the fired brass bucket. At first, I thought the ring was because the brass has been shooted to almost "death". There is a ring outside AND inside that I can feel with a paper clip.

It looks like it is the manufacturer who did that. Anyone can explain it please?



Thank you

Wow.......

Has to be excessive headspace, quite excessive, whether fixed or caused from serious over sizing.

My understanding is that many civilian Russian arms have to be manufactured with rings in the chamber, to help identify the weapon that fired the round as civilian and not military. The ones that I've seen do this all had the ring up by the case mouth, bit this looks very similar to that.

Interesting tid bit about the russian rifles. The rings are very precise and consistent.

Greetings,

The ring is inside too. Exactly like when brass stretch.....

Thank you

I'd have to go with the headspace theory.

Are those primers as flat as they look?

My brother bought some Silver Bear .30-06 ammo and it came out of the box with those rings on them. That was the first time I'd ever seen it. It was steel cased ammo.

new technique by manufacturers to prevent re-loading?

Some Russian ammo has that ring. I've only seen it on .30-06 though.

I found a bunch of steel cased russian 30-06 that looked identical, and I thought it was headspace too. It went in scrap anyway because it was steel.

Anybody seen any of this before firing? It may be that it was made too short of headspace.

Anybody seen any of this before firing?

Yes.
The Russian stuff my brother bought was identical when new and unfired. It was cheap too, like $9 a box and actually shot really well in his rifle.

Who is the manufacturer? I can not read the markings on the cartridge head, what are they?

 

[kutter]

Looking at that picture, I don't believe that it is headspacing issue. It all appears too uniform. Additionally, look at the second case from the left, the line at the top of the indentation sure looks like it was machined to me.

I would bet that it came that way. Why, well that is anyones guess.

Looks like Russian/Comm Bloc ammo. I think the headstamp includes Cyrillic letters with the ".30-06 SPRG".

 

[jerkface11]

I think it's golden bear. See if a magnet sticks to it.

One the right hand side of the 2nd case from the left, the ring looks like it is still rather deep. Being this is brass, and the location should be well ahead of the webbing, wouldn't one expect the pressures to flatten the ring all the way out? Assuming this is Russian ammo mfg'ed ring, of course. since the ring is still there, would that imply the brass is pretty thick on these samples or maybe the loads are relatively light?
Just wondering why the ring is still physically indented after firing.

 

[jerkface11]

If it's golden bear then the cases are brass washed steel.

Not the first time for this type case, the link above is useless and has no value, it starts like "Once upon a time" same as "So I purchased some brass on-line".



Same with "The donut", the donut that is created when sizing a case with the bushing backed out, then the question "What caused this?" I create donuts when I form wildcats or when the brass can not make the turn inside the neck/shoulder juncture, others form donuts when the bushing is not low enough to prevent them.

I've never seen rings like that. Ugly!

But I've seen the headstamp before. There are three Cyrillic letters that correspond to BPZ in English. It stands for Barnaul Cartridge Works (Barnaul Patronnyi Zavod in the original Russian). Or so Google tells me...
