72. Ballistic Basics - Twist Rate

I am kicking off a new mini-series called "Ballistic Basics" where I explain concepts, measurements, and important practices or theories related to shooting. Most of these concepts will have an emphasis or practical application in long-range rifle shooting, hunting, or reloading, but most will also apply to shooting a variety of weapons and disciplines. In this first "Ballistic Basics" episode, I am discussing twist rate: what the term measure, what it measures, why it is important, some historical examples, and even how to measure the twist rate of your own gun. Enjoy!
