Why is Ammo Measured in Grains?

Why do we measure modern ammunition using an ancient unit of weight from the Bronze Age? We finally explain the mystery. In this video, we break down exactly what a "grain" measurement is, where the term originates, and why it is still the universal standard for measuring both bullet weight and gunpowder charge in modern ballistics and reloading. We will trace the fascinating history of the measurement back to actual cereal crops and show you how it translates to precision shooting today. If you are a reloader or just a firearms history enthusiast, understanding grain weight is fundamental. If you enjoy these deep dives into ballistic science, make sure to subscribe to the channel!
