Ok I guess you missed the part where I said NATO brass is heavier than 308 WIN commercial.
Also I think you missed the part where I said most US manufacturers hold NATO brass to min specs 1.628 and some overseas companies who make to NATO standards slighty larger 1.633 or so can have problems in 308 WIN chambers.
So I am not sure if you read the machinist drawings that were provided. Dimensionally they are the same, except like I said some overseas PPU being one making ammo that headspaces at 1.633.
