We shoot steel all the time, but we arent supposed to shoot it inside of 15 yds. Being an instructor (so I'm at the range a lot) I have been hit with pieces of jacket and lead many times. Good glasses are a must. The fact that yours are hanging on chains will help dissipate some of the energy, where we have some rigid stands that are angled for deflection. Inside 15 yds can get scary, though we have done at times during combat courses. Try to give them a slight angle away from you and the back and downward that they already have should help too. Ryan
