I'm needing to pick up some 7.62 NATO ammo for an M14 type rifle. The manufacturer recommends 7.62 NATO. I understand why through a bunch of reading, brass thickness/pressure etc. Perusing the webs I see straight .308 Win, and 7.62 X 51, and some that says 7.62 NATO, on the label. Is ammo that's labeled 7.62 X 51 and 7.62 NATO the same? I'm hoping to get reloadable brass. So some countries stuff that's been in caves since 1950 with berdan priming isn't preferred. Nor is steel case seeing as it's not that much cheaper than brass is. Then, considering the times? I'm relegated to paying close to a buck a round...Though I did find this stuff which appears to be reloadable. I just don't know if "M80" means NATO. Or if it's crimped?
