No, it indicates that they were fired in a HK91 or similar rifle. They may look bad, but resizing them and reloading them is no problem.

I have only incountered the "splines" your referring to on military 7.62x51 Blank cartridges.
What USSR is referring to is the staining/deformation of a cartridge case that has been fired in a fluted chamber, as are found in most HK g3 style weapons.

Are they "splines" or a knurl? I have some 93 LC MATCH 7.62 brass that has a knurl around the head about 1/4 inch above the rim. The knurl is very light and only about 1/16 inch long. The brass is unfired and was manufactured with the knurl.

To Hexhead: The 93 LC MATCH brass I have is unprimed, so it is not crimped. I cannot speak for any MATCH brass that was factory loaded.

drack,
You're going to need to be a bit more specific or show us pics as to what you are talking about regarding these "splines".

Does it look like this?
308 from HK
Then it has been fired in the HK chamber with the flutes as mentioned above.
If it looks like this,
then it's a blank. Typically 308 military blanks look like this

What you describe sounds very close to these shells but they are not marked "match". I have a small amount of 30-06 brass that read "match", but these read L.C. 82 but also has NM also. Could this really stand for National Match? I would send a picture of these rounds but I'm not familiar with how to paste it in this message.

Drack -- which picture does it look like.

Do the splines look like they might have been shot through something similar to this?
If so blame HK's inspiration. Neat concepts and performance.....bad for reloaders. Becoming more common.
Does that nonsense come in .223 / 5.56 as well? If so it answer a question on some range pick up I've got.
I'm guessing yes. Does it render the case scrap? That's where mine went....

To drack:
The letters on the head "NM" were also used to denote MATCH brass.
Follow the link below. There is a discussion and pictures of knurled cases.

Not scrap at all. I resize and fire it. After firing a time or two the lines disappear and the brass will last a while longer just like your regular brass.

Yep, two flavors: HK93 in .223 and HK91 in .308. As previously stated, the brass may look bad, but it gets ironed out when fired again in a normal chamber.

The HK flutes are also in the MP5/HK94 9mm series as well. Though they are not as pronounced in the 9mm.

I don't think anyone addressed the crimper primer issue. All match brass that I have ever shot or reloaded is not crimped. Crimps are not needed in match brass since it's not generally fired out of automatic weapons where a loose primer could shut down the weapon. Not good in combat.

True. Any brass marked "Match", "NM", or "LR" does not have crimped primers.

late double post
Mr. GPB: (& you other kind folks):...I viewed the link you gave me and YES----my brass is exactly the same. But the "splines" on my cases are very light,..not near as deep as the diagram would lead you to believe. You fellows are really nice to help me out with this info.
I'm very glad that I joined this forum. Drack in Florida

What is the purpose or benefit of having a fluted chamber?

When i sold 308 brass, i pulled all the HK stuff out. and threw it to the side. loaded a couple and fired them out my Rem 700. cases came out straight again. so i sold off the normal 308s, and started loaded the HK stuff. a bunch of my buddies were asking me questions about it. I told them watch this....HK goes in, smooth brass comes out. they all laughed.
