Folks, please share your experience. I'm looking into starting with steel target shooting with pistols. Is there a limitation to how rapidly one can safely shoot at a swinging (chains) steel target? (Target in question is 11x13 inch 3/8 ar500 steel, 9mm ranging to 357 mag) The hanging option seems more affordable however I would like to able to shoot with some speed. The alternative method:mounting bracket options for a vertical 2x4 stand cost a pretty penny.
