This target has a yellow disk which when struck falls, the size of the disk can be changed to make the shooting more difficult. Reset by pulling on a string (supplied) so no traipsing up and down the range.
You should always take precautions when shooting against ricochets and shots which may cross your boundary. Ensure you (and those around you) wear eye protection, be aware of where missed shots may end up and where richets may go to. It is an offence to allow a pellet to go beyond the boundary of the land on which you shoot.
