Leggendo l'interessante manuale suggerito da Cris ad Eniac( Cerca in rete il documento SW010-AD-GTP-010) ho trovato qualcosa che non mi torna.
Nella sezione 7,62 nato ho trovato questa nota.

Si tratta della solita 7,62x39 M43, solo che credo che sia utilizzata componentistica, inneschi, palle e polvere, di origine occidentale.
I proiettili sono di peso fuori dagli standard russi.
