I have a Gamo CFX that I use for backyard plinking. I would like to reduce the noise this rifle makes, but I am aware that silencers do not necessary work on springers. So, any hints/tips/advice on how not to bother the neighbours (when shooting!) would be appreciated. Previous neigbour did not mind, but the new occupants are real bunny huggers and totally anti-gun. Oh, and before I get flak on this, my backstop is a 2mm steel pellet catcher against a 3m high brick wall, there is a 2m high wall on the left, my house on the right and a double garage behind me.
