Description
Vihtavuori 3N37 is a medium-fast burning powder specifically designed for handgun applications. Renowned for its superb metering properties, it features a fine-grained tubular shape that promotes precise and consistent dispensing, making it an excellent choice for competitive target shooting and precision load development. 3N37 exhibits excellent temperature stability, providing consistent performance across various environmental conditions, which is particularly beneficial for maintaining accuracy in variable weather. It is well suited for a range of popular handgun calibers, including the 9mm Luger, .38 Super Auto, and .40 S&W. This propellant is particularly favored for high velocity loads due to its ability to consistently produce optimal pressures and velocities. When developing loads, reloaders should note that 3N37 provides a clean burn with minimal residue, contributing to longer barrel life and less frequent gun maintenance. Vihtavuori's reputation for quality ensures reloaders receive a reliable powder that meets the exacting standards of precision shooters and competitive reloading enthusiasts.
