Description

Vihtavuori N310 is the fastest-burning powder in the Vihtavuori N300 handgun series and the top pick of competitive Bullseye pistol shooters worldwide. Known for its outstanding accuracy and exceptionally clean burning, N310 has earned its reputation across decades of competition use, originally introduced as N14 in the old Vihtavuori catalogues.

A single-base, tubular powder with grain dimensions of 0.7 mm length and 0.6 mm diameter, N310 meters smoothly and consistently through reloading measures thanks to its small, near-symmetrical grain size. It is one of the most porous powders in the Vihtavuori range, and porosity drives burn rate. N310’s structure delivers the fast, clean burn that pistol shooters depend on for accurate, repeatable loads.

While N310 shines in light target loads paired with light projectiles, it is genuinely versatile. Handloaders use it successfully with heavier bullets, and it is well regarded for shotshell reloading, including premium 24 gram target loads. It is also a common choice for blank ammunition production.

Pro Tip from Vihtavuori Try N310 with 185 gr bullets for .45 ACP target loads.
