Head stamps on 9mm Brass

[RugerSteve]

I have cleaned another batch of brass and was separating brands. Most of them are "R-P". What brand is that? Also have "F C, which I assume is Federal? Also have Winchester, and a lot of misc, like Speer, Tulamo, Hornidy, Blazer, etc.

Remington Peters then there is Federal Fartridge/Case, at one time there was TW, TW was operated by Federal, The T stood for Twin as in Twin Cities. When Federal started operating the Twin City arsenal they only loaded shot gun (before they started operating the TW arsenal).

I have run across a few FC stamps with NT next to it. Does this mean NATO?

I believe NT stands for 'non toxic', meaning the primers use something else other than lead styphnate.

They are notorious for being difficult to reload.

NT means non-toxic.

This is the headstamp symbol that identifies NATO spec ammo.

This is the head stamp symbol that identifies NATO spec ammo.

That is also the symbol reloaders assume SAAMI uses in their drawings of case dimensions. SAAMI uses the symbol for chamber dimensions because the chamber has head space.

After the NT case is fired it means the primer pocket could be small primer size and the flash hole could be larger in diameter.

So do I need to sort out the NATO designated cases, or will they prime ok? I know I have seen several out of the 1000 that I went through last night

You may run into crimped primers in NATO spec ammo.

You'd need to remove the crimp before you reprime.

 

[FrankenMauser]

If you take another look at the Federal (FC) brass, you'll probably find multiple headstamps.

Federal uses these, and more, to indicate different manufacture methods and production plants:
FC
FC●
●FC
●FC●
FC●●
Federal●
●Federal
●Federal●
Federal

The dots indicate extruded cases, rather than drawn. The number and location of the dots indicate the production facility.

Other than military brass, they're the only domestic company that I know of, that uses markings in that way.

Occasionally, you'll find the "dot" (●) markings on Speer, Blazer, or CCI brass, as well. ...They're all part of the ATK family, along with Federal.

Someone told me that the NATO spent primers are usually hard to get out. Some of the ones that I deprimed, came out easy.

I picked up a lot of Tulammo brass at the range, knew it was once fired. Sadly, it only held up for a couple of reloads, started to bulge near the base. Not saying don't use it, just don't expect it too last too long.

The are not very hard to get OUT, its getting the new primer IN which suck. You will have to remove the crimp. If you do not know how to do that, just ask, we all have different methods, many of then are fast and easy and you likely already have the equipment you need. You can tell by looking if it has a crimped primer after deprime, it wil look like it has a thin brass shaving on the outside of the primer cup
