If I wanted to be belittled and called a lier I'd post that I have shot through the spine and out the bottom of several bucks.So I won't.
Because God and Jeff both know thats not possible,so I'll only say that I have shot through the shoulder blade and out the far side ribs with 125 Gr thunderheads. I have on several occasions cleanly broke the off side leg bone with an exiting arrow that cut ribs off upon entering.
And your gonna love this one![]Ona stand along a hillside I had a nine point buck pass at about 15-18 yards broadside at eye level. As much as I hate to admit the shot did not hit where planed.[8D]Instead the arrow hit low and forward, breaking both front legs. The buck fell on his face breaking the arrow in three pieces,he sheared both ends of the arrow off leaving about a six or seven inch piece lodged in the very bottom of the chest cavity. A quick second shot ended the scenario.
Maybe it has some thing to do with the hardened steel chisle point on thunder heads but I have never had any problem breaking bones with them.
