Well, I know enough to work up 2 different loads for .308 Win. and 7.62 NATO brass. Because, in spite of your claims, there's a lot more than 10 grains weight difference.
Super-X .308 158.3 gr.
FC .308 164.7 gr. 165.7 gr.
R-P .308 166.3 gr.
RA 68 NATO 178.1 gr. 178.8 gr.
FC 61 NATO 178.6 gr.
WRA 68 NATO 178.5 gr. 179.3 gr.
But if you want to put on some kind of tough guy act over a warning about sizing 7.62 NATO to .243 Win. and not worrying about pressure increases, you go ahead champ.
Your advice is unsafe in this case, but apprently you don't care about that.
I kinda do. Sue me.

Here's a list of brass weights. And, wait! Regular Federal 308 win brass weighs even more then you have for the NATO stuff. And Lapua was the same weight range as you have posted for NATO.
So, once again, all brass can be manufactured to different specs. That's the longq Nd the short of it. There is absolutely nothing to support your idea that ALL NATO brass weighs more then commercial 308. Actually, there is info quite the contrary. And even with 20+ grains of case weight differential, the internal capacity was around 2 grains of differential.
Bottom line, work to any loads you make. Pet loads only work when substitutions are NOT being made.
