So, I have not been able to find a definitive answer on this. Is there really a difference in 7.62 NATO and .308 Win brass, or for all intents and purposes, are they the same? I've read claims that the 7.62 brass is thicker and will need to be downloaded, and I've read claims that the difference in thickness is negligible. The internet being what it is, people love to pass along myths and hearsay, so I was wondering what the truth is on this.
I have a pile of .308/7.62 brass and since this is not going to be for anything even resembling a precision rifle, I'm wondering if I should even bother sorting and separating the brass. I'm going to be reloading to 7.62 NATO specs, so I'm thinking that if I do my load development in 7.62 cases, the worse case scenario at that point would be the loads in the 308 cases having slightly less pressure and a slight POI change.
