Winchester Ammunition

[pendennis]

I have several boxes of Winchester 7.62x51 ammunition. The projectile is the 147gr FMJ. It functions perfectly in my M1's, M1A, and Panther Arms LR308. It's also very accurate. It's commercially sold, and comes in the white box.

The case heads show "WCCC", 2-digit year, and the NATO cross imprint.

Is this ammunition MILSPEC; i.e. crimped primer pocket, military thickness, etc.? Nothing on Winchester's web site states any more detailed specifications.

I think the NATO cross means that it's built to NATO specs. So, unless it's reloads, it's mil-spec.
