One of my more popular posts was Where does the bullet go?. I am somewhat of an expert on small arms exterior ballistics (I wrote Modern Ballistics) but while better than most people on terminal ballistics I usually refrain from saying much on the topic. Greg Hamilton and his colleagues at Insights Training are much higher on that food chain than I am. Although John Fogh doesn’t mention it I know a little bit about the research Insights has done on the topic over the years.
John gives us some of the research results on Terminal Rifle Ballistics.
