I ran 500 rounds of Wolf through my A4 just to see what would happen. I had to tighten up the headspace two clicks to get reliable operation, but then it ran just fine.
I have also run many thousands of the old Norinco copper-washed steel cased ammo with no problems except it broke several firing pins. Since they are cheap and easy to replace, I don't regard that as a significant downside. I would break one per shoot as a rule, then have no further problems.
