The buck I killed back on the 6th had more fat than any deer I have ever seen. He had 2 big globs of slimy fat inside the body cavity that were probably 18 inches long and bigger than your fist around. I don't know what an arrow would look like if it happened to pass right through one of these globs, but it might coat the arrow, I don't know. My buck only went 40 yards, though. Had a breathing problem.
