I was going to say, if you are having trouble finding him, I'm sure Ray Charles could give you a hand!
The good thing about a blood trail like that is that they are easy to follow if you need to track the deer. But with a blood trail like that, you seldom have to look far. Good job.
The only time I ever seen blood splatter like that was with a deer I shot with a Precision Rifle Dead Center .40cal bullet. Hit it just above the heart, double lung with a BIG exit wound low in the chest. Deer ran maybe 75 yards, and there was so much blood it looked like a scene from CSI.
