Vihtavuori N350 Smokeless Gun Powder

Looking for Vihtavuori N350 in stock? As the slowest-burning powder in Vihtavuori’s entire N300 series of single-base handgun powders, N350 is purpose-built for very heavy loadings and top-end velocities and energies across a broad range of pistol and revolver cartridges. For safe charge weights, always consult Vihtavuori’s official load data before loading.

N350 is especially well suited to loading powerful rounds in popular calibers like 9mm Luger, 10mm Auto, and .45 ACP, and it’s a strong performer in high-intensity cartridges including .357 Magnum, .357 SIG, .40 S&W, .38 Super Auto, .38 Special, .357 Remington Maximum, and .41 Remington Magnum. It shares the exact same grain dimensions (1.0mm length by 0.8mm diameter) as its close relatives N320, N330, and N340 — it’s the powder’s porosity that sets N350 apart and gives it that slower, higher-energy burn characteristic.

N350 is widely used across pistol shooting, and particularly favoured in practical shooting disciplines where top velocity matters most. It also performs excellently in shotgun shooting with heavy hunting loads, especially at 36 grains or more, making it a genuinely dual-purpose option for reloaders who load both handgun and shotshell ammunition. If you’re loading medium-power pistol cartridges instead, Vihtavuori N340 may be the better fit for your needs.
