With AR500, make sure to find targets that have been cut either with a water jet or underwater plasma. Standard plasma cutting, which is what some of the cheaper mfgrs do, will de-temper the edge of the gong and hits there will ding it up bad. We tend to shoot well inside the 50 yard mark so we're very attentive to anything that might cause an unpredictable ricochet.
