I wouldn't exactly say no effect...
Steel cases can cause some reliability problems. They have to be lacquer coated, plated, or polymer coated, to prevent them from corroding. Lacquer coated cases can start to form a type of glue in the chamber, and this can occasionally glue a case into place. Steel cases also don't 'rebound' as well after firing. When a round is fired the case is pressed against the chamber walls by the pressure. After the pressure drops a brass case will tend to shrink a little bit away from the wall, but steel doesn't shrink as much. If there is a burr in the chamber, it might not hang up brass but it might hang a steel case in place.
I've had the unpleasant experience of getting a lacquered case glued into a Mauser and it was a B**** to get it out...
