I hit him just behind the shield. I had already hosed some of the dirt off of him before I took the pics, but roughly where the blade of grass is on the picture under the one with the dog. I haven't retrieved the arrow yet, and he may have knocked it out or broken it off inside of him. I was using my thunderchild which is 55# at my draw and beeman mfx classic 400 with 75 grain insert and 175 grain tigershark heads. I will tell you that I feel very lucky, because he must have been angling slightly away and it was either a killing shot right off, or he laid on the arrow and made it a killing shot(when he squeeled). My thunderchild is a great bow, and has a few kills under it's belt and hasn't let me down yet. That being said, I don't believe in the easter bunny, and I don't believe there is any chance that my setup was going to penetrate that shield. It was like plywood. I am not going to blame the lack of a bloodtrail on the broadhead. The fact that I hit a little back and the crazy thick hide and very thick fat closed things off pretty well. As as side note, this guy didn't have any external testicles. I didn't gut him, so maybe there is one inside, but I found a single small testicle that was right at his groin. I wonder if this had something to do with how large this hog was. I had a friend tell me that it was, and I know that in the horse world, geldings usually grow larger than stallions. Who knows. I don't know if I will ever kill another one larger. I have been on a few paid hunts and never saw one this large.
