Is there a consensus "best" book, online course or anything else that I can use to learn more about ballistics than what's in reloading books? I have the Lee Modern Reloading Second Edition book and while it has a few pages on pressure, velocity and such it's not nearly enough for me to really understand it so some of the data in the charts doesn't make sense to me. I'm not really seeing anything on Amazon. Right now I'm interested in handguns vs. rifles if that makes any difference.
