Steel case puts more stress on your extractor. Not the end of the world but the saving must worth it.
Now that Norinco 7.62x51 (450$-600$/1000) seems sold out there's no great steel bargain.
Don't buy Barnaul at 1$/round.
Try to find PMC, Lake city or Hirtenberger surplus at 650$-750$/1000. Those are brass case ball ammo that should provide good to excellent accuracy. I had many rifles that shot sub-moa with that PMC bronze.
Wait for sales at SFRC (now), Canada ammo, Tenda or Trade Ex. Buy it cheap, stack it deep.
