.308 Winchester vs. 7.62x51

This is pretty cool and a good look at an issue I know causes a lot of questions out there.

I have a rifle chambered in .308 and always just buy .308 Winchester but it sounds like I could have strayed and gotten into some 7.62x51mm if the price was right.

Thanks to BulkAmmo for look at .308 vs. 7.62x51mm ammo.
