I would like to set up a range in my back garden and would welcome advice on a suitable backstop to safely prevent any pellets leaving the boundaries of my property. The back garden backs onto fields with a wooden fence and hawthorn hedge. Unfortunately there is a footpath occasionally used that runs behind the hedge so it's imperative I have a safe means of backstopping the pellets. I have 3 panels of 3/4 inch marine ply hinged together in a c shape to mount the target on.
All advice would be gratefully accepted.
