Further, the Russian bullets weren't swagged and could vary by up to .02, so if you want to pick another friggin' nit, your CUPs might rise by a few hundred but you probably won't notice this unless you are pushing max compressed loads on a bench gun.
Dead Corpse, why take a chance with chamber pressure? There are zillions of .308 diameter bullets out there for use in the .308 Win, 30-06, etc.. Save the Russian diameters for the Russian cases.
BTW, your first link only shows what I have stated earlier: it is acceptable to load a .308 diameter bullet into a Russian case (but not the other way around). Your second and third links reference only the Russian cartridge.
For anyone who will listen, NEVER load the larger Russian bullets for use in the smaller .308 caliber rifles (.308 Win, 30-06, 30-30, etc.. If ain't worth it.
