.308/7.62x51 is the same ammo from a bolt action point of view.
The difference is that .308 hunting/commercial ammo comes in a variety of bullet weights and velocities, while NATO spec is all 150 grain at a specific velocity. So, commercial ammo may or may not be reliable in a military auto or semi-auto because of the different pressures, bullet weights, recoil impulses, etc. You might bend an op-rod or something shooting a hot 180 grain commercial load in a military rifle.
The reverse is not true with a bolt action rifle. It should feed anything out there.
However, the most popular hunting loads are also 150 grain and so practicing with NATO spec ammo usually doesn't require re-zeroing for your hunting loads. If you want to hunt with say, a 165 grain load you may have to adjust a few clicks after zeroing with 150 grain NATO loads.
