Vihtavuori 3N37 Handgun Powder

Vihtavuori 3N37 handgun powder was originally developed for .22 rimfire cartridges and has since proven to be a versatile, reliable choice for competitive handgun shooting disciplines.

This tubular, porous powder features symmetrical grains measuring 0.6 mm in length and 0.6 mm in diameter, allowing smooth, consistent metering in powder measures. Its burning rate is close to N350 and falls within the medium range of Vihtavuori handgun powders.

An excellent choice for 9 mm major loads in IPSC open competitions, 3N37 is also popular among USPSA and IPSC practical pistol shooters. In addition to practical shooting applications, it is widely used as a submachine gun powder. Like all Vihtavuori powders, 3N37 delivers consistent performance, extreme precision, and clean burning.
