Hi,
They are predominantly for our own use we are falconers and keep and fly our own birds. If we sell them obviously no one can guarantee 100% lead free as someone may have had a pop shot at one that is just out of range which a pellet has made contact with but not killed. What we do not want is people shooting with lead and then trying to pass them off as steel shot. A pigeon with a lead pellet in it when shot with steel is very rare. (From our experience)
