I would definitely consider the 500gr XTP. My water buffalo as Franchise was saying took 2 370gr penetrators and he just stood there. It punched a perfect half inch hole with no "SHOCK" to the animal. The 385gr BCHP hit him with authority and put a hurting on him. Not only did it break bone but it also tore meat. The penetrators have thier place in hunting just on something like a boar with a big shield. So you make your decision.......
