This video explains the dangerous phenomenon of Deflagration to Detonation Transition (DDT) in firearms. Professional gunsmith Guido details how gunpowder normally deflagrates, creating controlled pressure. He warns that DDT, where gunpowder detonates, can occur due to improper loading, especially with low powder charges in long cases, leading to catastrophic firearm failure. The video emphasizes meticulous reloading practices to avoid this risk.

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.

This video provides a detailed ASMR-style disassembly of a .410 gauge shotgun shell, revealing its internal components. The creator, demonstrating a subject matter enthusiast's approach, meticulously weighs the lead slug (7.50g) and smokeless powder (0.62g) using precision tools. A burn test of the powder is also conducted, offering insights into its combustion characteristics.

This guide details critical safety considerations when reloading with fast-burning, dense powders like Accurate No. 2 and flake powders like Alliant Red Dot. It highlights the risks of double charging and bridging, emphasizing the need for meticulous verification of powder charges using scales and visual inspection. The instruction comes from an expert with over 20 years of reloading experience, offering practical advice for safer reloading practices.

This video provides an expert-level overview of different shotgun powder types, focusing on visual characteristics and burn properties. The instructor, demonstrating high authority, showcases Winchester, Sellier & Bellot (vintage), and Zuber powders, highlighting their flake shapes, colors, and ignition characteristics. It's an informative session for those interested in the specifics of ammunition propellants.

This video explores the critical differences between various gunpowder types, emphasizing that 'gunpowder isn't gunpowder.' It highlights how burn rate, powder shape (spherical vs. flake), and case volume significantly impact reloading outcomes for specific cartridges like the 300 Blackout and 308 Winchester. The discussion stresses the importance of consulting resources like the Hodgdon Reloading Data Center for optimal powder selection based on bullet weight, desired velocity, and pressure requirements to ensure safe and effective ammunition.

This video provides expert guidance on selecting appropriate powders for .223 Remington Short Barreled Rifles (SBRs) and AR pistols. The instructor emphasizes the critical role of powder burn rate in relation to barrel length, explaining how faster-burning powders are necessary for efficient combustion in shorter barrels to avoid unburned powder and excessive muzzle flash. The discussion covers how bullet weight influences powder choice and provides a narrowed-down list of recommended powders for these specific applications.

This video provides a quick tip on selecting the right powder for reloading. It emphasizes consulting reloading manuals for caliber-specific information and understanding the difference between fast-burning powders for pistol/shotgun and slower-burning powders for rifle. The choice also depends on whether the goal is maximum velocity or economy loads.

This guide, presented by an expert reloader and firearms educator, details the critical aspects of understanding reloading powders. It covers the historical context of powder manufacturing, the importance of reloading manuals, and how to interpret burning rate charts. The video visually compares different powder types (flake, ball, extruded) and discusses practical considerations for powder measurement and accuracy, suggesting that meticulous trickling may not always be necessary for achieving excellent results.
