Description
Vihtavuori N320 is a fast-burning, single-base pistol powder, meeting the demands of precision-driven reloaders. Known for its consistent burn rate of 9.3, it is well-suited for a range of handgun calibers, particularly in crafting subsonic loads. This powder has garnered acclaim for its uniform granule size, facilitating excellent metering through powder measures, an attribute prized by those seeking precise charge weights for competitive shooting. Its application extends primarily to pistol cartridges such as .45 ACP, 9mm Luger, and .38 Special, where achieving optimal subsonic performance is critical. Marathon reloaders will appreciate the stability of N320 under various temperature conditions, ensuring consistent velocities and pressures across different environments. In load development, the powder's fast-burning properties allow for a significant reduction in recoil and muzzle flash, appealing to competitive shooters and those seeking a softer shooting experience. Handloaders trust Vihtavuori for its rigorous quality control and reliable performance, making N320 a staple component in the pursuit of precision and performance.
