This video by Boondock Ballistician delves into the critical role of propellants in firearm performance, particularly for small caliber ammunition. It breaks down propellant types (single, double, triple base), explaining their chemical compositions and typical applications. The discussion emphasizes how propellant properties like burn rate, grain geometry (degressive, neutral, progressive), and web thickness significantly influence pressure, velocity, and overall system performance. The importance of a robust ignition system for uniform propellant combustion is also highlighted.
