Understanding Smokeless Powders: A Brief Overview for Reloaders

Hodgdon H380 is a smokeless spherical propellant, a key distinction in the world of reloading. Understanding the basics of smokeless powder can help reloaders appreciate the engineering behind H380.

• Smokeless Powder vs. Black Powder: Unlike black powder, which burns rapidly and produces a large cloud of smoke and fouling, smokeless powders burn much slower and produce significantly less residue. They generate gas pressure more efficiently, allowing for higher velocities and more consistent performance.
• Spherical (Ball) Powders: H380 falls into the spherical or "ball" powder category. These powders consist of small, uniform, ball-shaped granules. Their manufacturing process often involves extruding nitroglycerin and nitrocellulose mixtures through dies, then cutting them into small cylinders, which are then rounded into spheres. This shape contributes to their excellent metering capabilities, allowing them to flow smoothly through powder measures and fill cases efficiently.
• Burn Rate: Every powder has a specific burn rate, categorized on a relative scale from fast to slow. H380 has a medium-slow burn rate, making it suitable for larger case capacities and heavier bullets in its optimal calibers. Matching the powder's burn rate to the cartridge's volume and desired bullet weight is crucial for safe and efficient pressure generation.
