some Nato 5.56mm ammo berdan primed?

[flynlr]

I ran across this brass in a mixed lot of fired brass

and after resetting my lee universal de-capper pin back a couple times
I took a look inside the cases to see the berdan 2 flash hole dot special.

anyone have a clue what ammo this is . I noticed the 3 staked crimp on the primers also.. needless to say though the brass is beautiful , it seems worthless to me.

4 possibilities that I could find at http://cartridgecollectors.org/headstampcodes_bottom.htm

SB Arms Corporation of the Philippines, (formally Squires Bingham Co.) Marikina, Republic of the Philippines

SB Empresa Nacional Santa Barbara de Industrias Militares SA, Toledo, Spain

SB Israeli Military Industries, Tel Aviv, Israel

SB Sellier and Bellot, Schoenbeck/Elbe, Germany

Even I can't find berdan primers to attempt to reload these

My guess?

I would eliminate IMI and S&B as all the brass I've seen from them was boxer.

Don't know anything about Phillipine ammo but I would think any ammo amking technology they have they got from us. My guess is it's Spanish.

what's the difference between berdan and boxer primers?

what's the difference between berdan and boxer primers?

One is reloadable (boxer), the other isn't (berdan).

More specifically:

Boxer - invented by a Brit
Dominant primer system in the US
The anvil is a part of the primer
Single, central flash hole in shell case

Berdan - invented by an American
Most commonly used in Europe
The anvil is part of the shell case (in the center of the primer pocket)
Two offset flash holes in shell case

Berdan primers are hard to find and expensive in the US. Also, the location and type of the flash holes makes depriming laborious, and takes special tooling (or home-made ingenuity.)

with Spain being in Nato . that is a possibility there is a Nato Cross on the rounds.

You can reload Berdan primed cases.....it's just not as quick to pop out them used primers.

Cant be Squires Bingham... they are a retailer.
"Their" ammo is headstamped AP for Armscor Precision.
(BTW, everything we presently know/do re: cartridges is from you'se Amerikanos)

SB likely stands for Santa Bárbara of Spain, which was acquired
a couple of years ago by your General Dynamics: They are no longer ENSB
(Empresa Nacional de Santa Bárbara ), but "General Dynamics Santa Bárbara Sistemas"
