Check the G3/CETME boards. The fluted chamber and associated ejection IS an issue. Most spent casings from an unmodified rifle of this type should *not* be reloaded.
These are the fairly typical leftovers from firing a G3 or CETME-type that’s working properly.

The fluted chamber and resulting violent extraction of the action results in nice, reliable, positive ejection, but it’s hell on the brass and renders it unsafe to reload.
You can put a port buffer in the thing and that will cut down on the amount of brass that’s totally destroyed, but anything that looks like the two pics above (which most will without a port buffer and even a significant minority will even with a buffer) needs to be tossed instead of reloading.
Yeah, those are not reloadable.
I have one that does that and one that just leaves the gas lines from the fluted chamber. I think those are OK.
The beat up ones probably need the delay time on the locking rollers looked at.
AK based .308s beat the crap out of the brass too.
My VEPR beats the crap out of brass
