Description
Reload Swiss RS 70 is a high-performance propellant with a slow burn rate characteristic, ideal for rifle loads where maximizing velocity and consistency is crucial. Designed for magnum rifle cartridges, RS 70 is particularly popular among reloaders developing loads for calibers such as the .300 Winchester Magnum, 7mm Remington Magnum, and .338 Lapua Magnum. Its extruded grain form ensures uniform metering, contributing to precise load consistency and reliable ignition across diverse reloading equipment. RS 70 is well-regarded for its excellent temperature stability, providing consistent performance in varying climatic conditions—an advantage for competitive shooters and hunters requiring dependable results. During load development, users will appreciate its broad application across large-volume cases where both energy and efficiency are paramount. The powder's chemistry is formulated to generate lower barrel temperatures, extending barrel life—a critical consideration for high-volume shooters. As an offering from Reload Swiss, RS 70 benefits from the manufacturer’s reputation for producing clean-burning and precision-oriented propellants, making it a preferred choice for those demanding the utmost performance from their rifle handloads.
