Do you hang your metal plate so it can swing when hit or is it firmly anchored? If it is firmly anchored, is it angled back at the bottom or perpendicular to the ground? I occasionally see richochets with steel shot from the metal posts I use as support for my wooden target board, but they have not come back to me at 40 yards. I have heard them bounce off the garage siding about 15 yards away from the posts, however. I think if the plate was angled with the top slightly forward, or if the plate could swing from the top, the possibility of richochets would be reduced.
