One other thing, I don't just load indiscriminately with the same powder charge in all cases. I sort cases by brand, or at least by weight. Federal brass is often heavier, = lower capacity, so charges must be reduced a wee bit. If you don't do that, and you're already loading a max load for other brass, over max pressure is likely, and corresponding poor case life.
That's been my experience.
I don't buy any Fed brass, but all my 308 hulls come from a police tac unit and they are all Federals.
Low runout and get fed .5-1 grain less powder as the Win. Rems I used to use to hit the same clock numbers.
No issues.
