NATO ammunition captured in the field could be used in the AK-47; not the case for our stuff. You put a soviet AK-47 round in an M14 and it will jam or worse.

I think stories like that might get started, when someone writes about using pulled .308 NATO bullets for reloading 7.62x39 ammunition, and it gets misinterpreted. I remember similar stories from years ago ("Jap rifles could shoot British .303 ammo, but not vice versa" ;^), that probably started the same way...

Funny thing My Russian rifles are chambered for .308 Winchester, well that’s odd enough, but you can shoot Nato .308b in them all day long, Now here is the rub.... I have Nato .308 rifles that I would never put .308
Winchester in

The .308 Winchester round runs at higher pressures,
Yup the civilian stuff is MORE powerful than the military grade stuff

With 5.56x49 and .223 its the other way around.

Both ammos will work but the military stuff runs at a higher pressure.

Sometimes I think they try to keep things confusing, but the legacy of the Kalishnakov is its simplicity

There's a version of the Dragunov which fires 7.62x51, which the Russians designed for the export market. Perhaps that's how the "fire nato ammo in AK" thing got started.
