Description
Rottweil's R 907 propellant is categorized as a medium burn rate powder, making it particularly suitable for rifle applications. Its burn rate offers versatility across various calibers while providing consistent performance. The propellant is a double-base powder known for its granular form, which ensures efficient and precise metering—a critical factor for consistent handloads. Handloaders will appreciate its stability in different temperature conditions, reducing variance in performance that might otherwise affect accuracy. R 907 is especially well-suited for calibers such as .308 Winchester and .30-06 Springfield, where its medium burn rate provides an optimal balance of velocity and pressure. When developing loads, experienced reloaders will find that starting slightly below maximum charges allows for fine-tuning to particular firearms, enhancing both accuracy and efficiency. Given Rottweil’s esteemed reputation within the handloading community for producing reliable and high-quality propellants, R 907 continues to be a favored choice for those seeking consistency without compromise in their rifle loads.
