12,7x81SR

[guardianangel]

Hi Everyone!

In the picture you can see an Italian 12,7x81SR Breda ammunition. The case made from brass; the projectile is also made from brass but it is covered with nickel. I dont know what does it mean the blue painting but the projectile stand from a solid brass core with some lead and the tip is filled with white-phosphor. So as you can see the base stamp (IV.): SMI 940. It is Italyan. OK. The following (III.) is unknown for me. The 2nd is a Hungaryan type: HA = Állami Hadianyaggyár, Weiss Manfred, Csepel, Hungary. I think the 1st is English but I would like to know moer&

So if somebody know anything about the ammunitions and its base stamps please write to me! Drawings and pictures are also very good.

The first can be a .50 vickers. But i don't know what 565 means.

and the headstamp

Hallo Racefiets

The first headstamp definitly belongs to a .50Vickers Long (12,7x120SR), like i showed. You are showing a .50Vickers Short cartridge, which has different headstamps and can not be confused with the "Long" cartridge.
565 stands for the bullet weight (in grains)

You both are right. It can't be a 12,7x120SR "D"-round. It has to be a 12,7x81SR, also known as "C"-round. Could it be possible that the headstamp belongs to a cartridge made for export?

Hi
Recent studies have shown that marking B*37* is not Italian
ball and crimping groove are not italian.
the B*37 case have 4 segmet to crimp the ball, italian used 3 segment

In the first 2 pics the Hungarian( 1s from left)
in 3rd and 4th pic charachters and method of marking are identical to hungaarian one.

did you have any other info about hungarian 12.7x81SR?

best regards
