John, I forgot about the "Kiss a lizard" for luck picture! Ha!Ha!
Lee, You can see the end of the arrow on the entrance side if you look close. It is in the crease of the front shoulder and dead center up and down. The exit is dead center under his neck. The exit cut his jugular veins. I guess you have heard the saying "Bleeding like a stuck pig" There was less than a half pint of blood in him when I cleaned him, it was all over the ground in the 75 yards that he ran.
These are the heads that Bill is making. I put them on my Lansky sharpener. I broke my ceramic stone so I finished them with the finish stone. They would shave you without a problem.
A good quality head, very sharpe (file or honed)in the right place will work every time. The blood trail depends on the exit and what it cut when it went through. Just my thoughts.
