Description
RS 20 by Reload Swiss is a fast-burning propellant ideally suited for handgun and pistol applications. Its burn rate of 8.1 places it prominently in the fast range, making it an excellent choice for high-velocity loads in common pistol calibers. The powder comes in a fine-grained, consistent physical form, ensuring excellent metering properties for precise charge weights during the loading process. RS 20 is specifically engineered for superior temperature stability, maintaining its performance across a wide range of environmental conditions, which is critical for competitive shooting or precision applications. This powder excels in popular calibers such as .38 Special, 9mm Luger, and .45 ACP, providing a reliable and clean burn. When developing loads, handloaders should consider its quick pressure peak, which is beneficial for achieving optimal velocity without excessive powder usage. Reloading with RS 20 offers the distinct advantage of consistent shot-to-shot performance, trusted by experienced reloaders for its dependable characteristics and versatility in various load configurations.
