Great hog Terry! That shield really is unbelievable till you see it for yourself. That big hog I shot last night of Sweat had a shield 1/2" thick. The weight of the shield pulled the skin off as we skinned it. Once we had the shields off we layed them out and it was all anyone of us could do to drive a knife through that shield. I wish we would have had more time to let some of the guys shoot at shields with lighter poundage bows. I was using a 75# Morrison with 640gr arrows and only got 10" of penetration at 15 ft.Hit was directly behind shoulder and took out both lungs.
