VihtaVuori 20N29 is a premium single-based, surface-treated smokeless gun powder specifically engineered for large-caliber and magnum rifle configurations. This specialized propellant was originally developed for military applications and follows strict Finnish Army standards. It features a significantly slower burning rate and a larger grain size than traditional N100 series powders to optimize performance in large-volume cases. It is frequently used for high-performance applications involving the heavy-bullet .50 BMG cartridge. Additionally, it is noted for supporting consistency in extreme long-range target shooting calibers such as the .300 Lapua Magnum and .30-378 Weatherby Magnum.
