Vihtavuori 3N37 Handgun Propellant - 500g

The Vihtavuori 3N37 Handgun Propellant is powder originally developed for 22 rimfire cartridges but has since proven to be versatile within all competitive handgun shooting disciplines.

3N37 is a tubular, porous powder with a symmetrical grain size, making metering a breeze in powder measures. Grain dimensions come in at 0.6mm in length and diameter.

This medium burn rate propellant is an excellent powder for 9mm major loads in IPSC open competitions and very popular in USPSA and ISPC practical pistol shooting disciplines.

Vihtavuori’s 3N37 has also widely been used as a submachine gun powder and was used back in the 1940’s by Sako for loading 9mm submachine gun cartridges.
