Good morning.

I'm just about to load up my first batch of .223. Does anyone have a list of base marks that would indicate military brass with swedged primer pockets?

Thank you for your assistance.

Scott

Sorry, I don't have a list. You can tell if the primer pocket is crimped just by looking at it. I hope I am understanding your question. If you have any questions on what the crimp looks like let me know and I will try and get some pictures.

I have a coffee can of range brass to start with. I'll check it while sorting to see if I can spot the difference.

With military brass, you normally have one of two different types of primer crimps; either a ring crimp or a segment crimp. A ring crimp is all the way around the primer, so it folds part of the head over into the primer pocket to keep the primer in. A segment crimp does the same thing, but only at a couple of spots around the primer.

Ring crimp:

just a little side note if you look at that top picture the headstamp has a symbol that looks like a + inside of a circle, that indicates that it is a NATO round therefore military, most US military rifle brass also says LC or RA on it, which is lake city armory and redstone arsonal where the rounds are made.

These links will tell you what markings are the military and standard brass.

Try 'Headstamp' not 'base marks' as search term and you will probably get better results.

Forty-five,
Thanks a bunch. I just ordered 2,000 1x (or so they say) brass. Funny brass, labeled Win NT with a silver primer. I am at work, so your first link is filtered out. I am very curious about this brass. They sold it as 1x, but what is with the silver primer?? I did a cursory search and " Win NT " takes you to endless windows links.

The brass was from Cheyenne Brass. Oh Yea, it was .223

Any imput??

I think the 'NT' is "Non-Toxic". I don't know all the details but I think it's ammo designed to be used in an indoor range. (non lead?)

Regards,
Dave

Sorry, but the "RA" stands for Remington Arms, not Redstone Arsenal.

"...Win NT..." It also uses small pistol sized primers in the .45 ACP they're selling. Keep it separated from standard brass. It's commercial, not milsurp.
"...why the primers are silver..." Just because. As daft as that sounds.
"...endless windows links..." You get that because 'Win NT' also means the Windows NT operating system.

Mallc,

Crimped in primers are a pain sometime. Almost all the major reloading equipment manufacturers make a crimp remover for military style primers.

Also, for what its worth. If you see a red, or similar color, painted ring around the primer (like your 9mm photos), that is an asphalt sealer to ensure that your bullet will go bang under damp or wet conditions.

Personally, I liked using military once fired brass. I've loaded 9mm military (US, and other countries) brass 5X before I tossed them.

Hope this helps.
