Description
Rottweil's R 901 propellant powder, possessing a burn rate characterized as medium, is specifically designed for rifle load applications. This powder is especially adept for calibers where moderate pressures and velocities are desired. Its physical form is a small flake, ensuring excellent metering properties through most powder measures, thus facilitating consistent charges that contribute to reliable shooting performance. R 901 is prized for its temperature stability, performing with minimal variance across a range of weather conditions, making it an excellent choice for reloaders facing diverse climates. Popular pairings for R 901 include the .308 Winchester and .223 Remington, where it strikes a balance between energy and control. When developing loads with R 901, users should pay close attention to published load data while conducting careful chronograph testing to verify velocities. Handloaders benefit from R 901’s clean-burning characteristics, which help maintain rifles' precision and cleanliness. Rottweil, with its longstanding reputation within the handloading community, assures quality and reliability in powder performance.
