These can be hung Across paracord to be shot at. They will swing when hit and spin around the cord. The centers are colored black with a black sharpie. I have currently tried these with Nerf Guns and slingshots, I am not to sure how well they would hold up with something like a BB gun or pellet gun (probably not well). It may be better to use some thinner type of cordage other than paracord as I was having issues with the ends of the paracord getting through the holes.
