Steel targets of 3/8ths or 1/2", in good condition and flat ie: not concaved or have rifle hit craters, you will have no problems. There is always a chance of a very small zinger stinging you, but this can happen with targets set at longer ranges. On impact, the bullet splatters radially at the same plane as the target, they don't "bounce back", the minute pieces that make up that splatter can fly like a damned frisbee and come back to bite you, but it's not because they bounced back.
