Get good bolts and fairly heavy chain like Craig said, as you are shooting some thumpers. Hang at an angle and resist the urge to shoot it up close just to see what it will do. All that lead has to go somewhere and the splatter can come back 15 to 20 yds and WILL DRAW BLOOD. By a couple of extra bolts and nuts and a can of paint and have a ball. Conveyor belting works very well for hanging targets also or the old belting off of a round hay bailer. With the conveior belting you don't worry about shooting it into.
