The FBI spent years studying wound ballistics and ammunition effectiveness. Still, if you go on a gun forum today and title a thread, “9mm v.45” you’ll start a firestorm. I found most of them overly opinionated and underly scientific, even as a teenager. Every popular gun magazine of the day had a seemingly endless stream of articles on wound ballistics.

The bullet entered his torso but failed to penetrate to the vitals. One of the felons was shot through his upper arm. That event shone light on ammunition effectiveness like no other in history at that point. in 1986, I was 15 years old and read everything I could about it. When the infamous Miami shootout was ended by hero FBI Special Agent Edmundo Mireles, Jr.
