I have a total of 100 pieces of once fired brass from Federal Gold Medal factory ammo. 80 pieces are ".308" GM (GM308M), and the remaining 20 are "7.62x51" (GM762M2).
My question is.. Other than cosmetic differences*, is there enough difference in these two subtypes of brass to segregate them? or can i simply treat all 100 pieces as being the same?
*the "7.62" brass is unpolished, has a simple "FC '11" (no NATO mark) headstamp and (felt like it had, mildly) crimped primers. the ".308" is polished like most commercial brass, has "FC 308 Win" headstamp, and no crimp.
