That "shockwave" of blood isn't really a shockwave at all. Think about punching some schmoe in the face. When he gets a black eye, its because the blood vessels under his skin have burst. A result of trauma. What you see there, is the result of trauma. Which I guess could be interpreted as a shockwave. However, I don't think that game animals die of severe bruising (unless it is to the brain, a gent on another forum I frequent just killed a nice buck with a "part the hair" shot).

I have never really been a fan of bullet energy, velocities or any of that sort. I have been a fan of accuracy, shootability, and usefulness. I will take a "less powerful" rifle that I can drive tacks with over a super mag with all sorts of numbers declaring how deadly it is, any day of the week.
