I would find a tough varmint type bullet for the 223 and use that. The Federal 55 grain load fits the bill it will exit on a behind the shoulder shot at least half the time but double shoulder shots it usually stays inside. If legal I would set up a feeder where the stone fence would be a back stop, if a bullet exits it won't have too much mass or velocity left to ricochet very far. Typically they would flatten out on rock or if at full velocity the would fragment, I would think only a glancing shot would be prone to ricocheting. Not sure whats available now but some of the 130 grain loads in the 30-30 would fill the same role.
