Unknown Nato rounds

I need info as to who made these rounds???Where do they come from???

Sherryl, the first one was made by PMP in RSA. The second also looks like a example from the same factory, but a better picture is needed to be sure.



Thank you Fede yes I know one pic is not so good however there is really nothing to see
the one has no stamp at all and the other only 7.62 thats all but thanks again
