I agree 100%. I think what happens is that a hunter makes that shot, they look for blood maybe even 50-60 yards and do not find any blood and assumes that they missed. Meanwhile about 20yrds later the chest cavity fills up and THEN they begin to drop blood.

I had this happen when I was about 11-13yrs old and I was all bummed because I couldn't find blood or hair and my dad went down over the side of the ridge about 70-80 yrds and then found blood. 20yrds later he was pilled up.
