I have shot at clay pigeons using a 12 gauge with pheasant loads that was okay. I was watching a show on history channel called the ultimate sniper I don't know how they did it in vietnam lying in the brush being real quiet waiting hours to take one shot just listening and waiting they gotta be able to hear the sounds around them. There was one sniper in Iraq who said he was deaf in one ear, he was sniping with a .50 cal ouch!
