If you are going to kill a big boar hog you have to shoot him through the shield,unless you are good at head shots or long nasty blood trailing.The ones I recovered on the AlexaCarrie hunt I was shooting a 70# bow shooting 188 fps and Wendsel broadheads.I made a complete passthrough on the boar hog through the shield and a complete passthrough on the sow through the neck,and the first shot went through both hips,breaking the hip,one leg and cutting the femoral artery.I lost 3 hogs that I didn't make passthrough shots on.Stone points made a heck of a blood trail till they broke the arrow and the fat closed the hole.
