Thanks Fuchs and Kiwigrunt for the technical details. I had the gut feeling this would be the case but you just gave me the right data.

Stan, when you say China would probably be already producing 7.62 NATO in Africa, do you have any idea of where?

What I see is that this could come from Khartoum, Eritrea, Somalia; all through Ethiopia or Northern Kenya. But that would mean the production plan would be located in one of those places.
Do you think it could be the case?

One of my colleague said that G3 where also used in Irak during Sadam times. Most of SAF guys were trained there. It would make sense that some of those ammunitions could come from Irak during the last years (at least during 2003 to 2006). Do you think this could be the case?
