Cardboard boxes work quite well, if you find your gun has a higher FPS; drape a blanket/towel inside the box and close the box. your shots ought to pierce the front and the towel/blanket will absorb the shot leaving it to just drop inside the box. Good for recollection.
If your shots are still hitting too hard you could wet the bottom of the towel, or weigh the bottom somehow. Either way, make sure it's secured at the top.
Works great with Tv or other large appliance boxes. Staple/tack a piece of paper to the front to use as a target, this may be exchanged at any point to 'refresh' your target area.
