7.62 .308 winchester same caliber, military ammo has thicker base for hotter machine gun loads, on a side note I reloaded .223/5.56 brass from Fort Hood and military brass needed a small base resizing die or it would jam in semi auto rifles and not chamber in bolt actions. Looking at the picture I'm pretty sure they're 308/7.62 just a close up shot photo.
