Brutal Attack...You seem afully opinionated with your statement. Just wondering how many deer or deer sized animals you have personally killed, versus what the Physics book says. If you can cause maximum trauma and provide an exit hole at the same time, you are darned well guaranteed that the bullet has certainly done it's job. And where do you even get the notion that pass-through shots leave "pencil sized" wound channels???? Certainly not in my neck of the woods with people who understand how to kill deer, and what to use to do it with.
