Figure 8-11. Single Segment Headstamp
Figure 8-12. Digital Photo of Two-Element, 2 x 180 Headstamp
The standard method of headstamping M1908 7.62 x 54R-mm ammunition is to mark it
with the year of manufacture and with a factory identification mark. The factory
identification mark is located on the top of the headstamp, while the year of manufacture
is located on the bottom of the headstamp. Headstamp factory codes, dates, and
cyphers are stamped and not raised. As stated above, some ammunition may have
cyphers, in addition to the year of manufacture and factory identification mark, such as a
star triangle etc. Many headstamp variations exist. At least one nation
(Yugoslavia) has combined the factory code and manufacturing year on the top
headstamp and placed the caliber (7.62) on the bottom headstamp. Some ammunition
can be found with either a headstamp entirely omitted or a partial headstamp with no
year of manufacture or factory identification mark.
