Simple explanation - The 7.62 chamber has a more generous headspace than a 308 and 7.62 brass is thicker in that area to prevent it from splitting when fired. 308 brass typically isn't reinforced and thus shouldn't be shot in a 7.62 chamber. 308 is also a generally higher pressure round so thinner brass + higher pressure + longer 7.62 headspace could be bad news.
