7.62 x 39mm cartridge, brass case, with the headstamp of 13 88 (13 @ 12:00 position and 88 @ 6:00 position), a product of Pretoria Metal Pressing Ltd Pretoria, RSA.
From the IAA webpage reference section, the 13 is said to be a load identification code and is not a manufacturer’s code.
Similar headstamps occur with 5.56 x 45mm and .50 BMG ammunition produced in South Africa.
Does the 13 in the headstamp indicated Model 1 Mark 3 cartridge or does it indicate something else?
If that is the case are there other Model/Mark’s of the RSA made 7.62x39mm and what are the differences?
