"but it deserves to be said that the .308Win is EXACTLY the same as the 7.62x51mmNATO cartridge. "
They are? Even though the specifications published for the two are always different? Go look 'em up in any reloading manual, the cartridges are different sizes.
It deserves to be said that you can USUALLY interchange the two without any damage. And, that you cannot interchange the two in accurized rifles without losing accuracy. You can match the load and chamber for one, or the other. And then run both, usually, but NOT with maximum accuracy, or complete safety.
Not my opinion. Go look 'em up yourself. Ask Sierra, ask anyone that makes reloading dies, ask DSA (who make chambers in both sizes), ask the NRA. The cartridges *overlap* and *typically* fall in the same dimensions, but they are not the same, and that can ruin your day. Or, just your score.
