Vihtavuori 3N38 Smokeless Handgun Powder

Vihtavuori 3N38 is a premium single-base smokeless handgun powder developed specifically for high-performance competition shooting. Positioned slightly slower-burning than 3N37 in the Vihtavuori N300 series, it is designed to deliver the high velocities and consistent pressures required for 9 mm Major , .38 Super and other full-power competition handgun loads used in IPSC and USPSA Open Division.

Manufactured in Finland to Vihtavuori's exacting standards, 3N38 features a fine tubular grain that meters exceptionally well through powder measures, helping produce highly consistent charge weights and excellent shot-to-shot uniformity. Its clean-burning formulation reduces fouling while maintaining reliable performance over extended shooting sessions, making it a popular choice among serious competitive handloaders seeking maximum consistency and accuracy.
