Same bullet diameter but different cases. Suppose you could use neck sizing die but not full length sizing die.

NO!!!!!!!!!!!!!!!!!!!
Unless your just de-capping with a generic de-capping die.
Any RE SIZING die will NOT work. Get a cartrige specific die for sizing. You will ruin your brass and probably your die if you try the other way. Eventhough both cases use a .308 cal. bullet, thats about where the simmilarities stop. Case diameter, shoulder, case length etc. are completely different.
