Seriously... don't even bother using chains. Chains will blow apart with a single rifle hit and you'll constantly be replacing them. You may be thinking to yourself... "I'm a much better shot than that, no way I'll hit the chain!" That may be true but steel targets are a blast to shoot and every one of your friends are going to want to shoot at them and they ARE terrible shots!
