Heck Ya!! I checked the UPS truck that was in the cul de sac this morning.... Nothing ;(
D.K.
That's the case with 5.56mm and .223, as in a rifle chambered for .223 cannot safely fire 5.56 Nato. However a rifle chambered for .308 can safely shoot 7.62X51 as the reverse is true. (i.e. The opposite applies; 7.62x51mm is fine in a .308 chambered rifle; .308, however, may not be fine in a 7.62x51mm rifle).
gonna make me buy a 308...
7.62 NATO round in .308 Win chambered rifle = go
.308 Win in a rifle marked 7.62x51 NATO = your risk.
Has to do with chamber pressure and possible differences in head space. (See post #69)

Democracy is not a spectator sport.
Actually it's more to do with headspace. 7.62x51 has more headspace so when you shoot, the brass case expands more. The 7.62x51 case has thicker brass, so it can make the expansion, but 308 win has thinner walls, so the case might rupture. Apparently, it's possible to chamber a rifle to have the correct headspace for both 7.62x51 & 308 win .
I also believe 308 win is slightly higher pressure as well. I believe 7.62x51 is pressure is specified in CUP, where 308 win is specified in PSI making a direct comparison tricky. But don't hold me to that.
