I was forced to shoot a bull elk in the neck nearer the head and in the center of the neck this year and the impact actually fractured his skull. I grabbed the rack and pulled and could see a line running right between the eyes like I had already made a cut to take the skull cap. One antler was cracked near the base too. The crack ran from the skull cap up about 1/2" into the base. I was using Barnes TSX bullets and would recommend them to anyone in a variety of calibers. I don't think they break up much. Once again you got a real slammer there CP.
