Default 7.62x51 headstamp ID ?

I have some 7.62x51 with headstamp F 78 61 any ideas who made it? My internet search turned up nothing. Thanks.

A photo will help. Is it US? At least 5 different countries use an "F". And, a lot of headstamps can be mis-read.

Ok so would it be safe to shoot in an M 14, it looks like it was made for NATO.

If it does not have the NATO cross on the headstamp it may be corrosively primed or have other undesirable charasterics.

Thats what I thought. So since it has the NATO cross I would think it would be ok to shoot.

Just because certain ammo has the NATO stamp it doesn't mean that it's always 100% safe. Afterall.....it's sold as SURPLUS and there could have been a reason for it being sold off.

Take a look at this article about 7.62x51 CBC ammo (bottom half of the page). Ok, ok it wasn't marked with the NATO cross but, the danger is there. Take note of what the importer of the ammo did about the situation.

Shot some of the Chilean 7.62 NATO in my tanker - worked fine. About as "hot" as the other common surpluses out there. Think mine was '76.

Ran 115 rounds of F 78 41 Chilean ammo this afternoon, not as hot as some countries, all shot fine, no case issues as reported in 73-75 years.
