Thanks for all the kind words.
I found the arrow, tip missing half way to the bull. The Bull ran about 80 yards from where I hit him and piled up as you see in the picture with 2 arrows and my bow. I took the quarters off without gutting him, but I cut the entry hole bigger to see if I could find the tip. the liver was in pieces, the arrow did not exit the opposite side but had a good 20" of penetration.
