Can anybody tell me if the headstamp FNM43-65 is Portugese ammo? That what it was advertised as but I was going to check.
By the way, I heard the NATO cross was a sure sign that surplus ammo is non corrosive. Any truth to that?

according to what i posted above its either mexican or portugese.The possiblity of having corrosive ammo is slim I don't think there has been any corrosive 7.62 NATO made since the very early 60's.I think there was some israeli stuff made in the late 60's or early 70's that was.

Agreed. I don't think any NATO is corrosive

I would lean towards it being Port.
