Vihtavuoris 3N37 handgun powder was originally developed for .22 rimfire cartridges, but has since proven to be very versatile and desirable within all competitive handgun shooting disciplines. The 3N37 is tubular, porous powder type with grain dimensions of 0,6 mm length and 0,6 mm diameter. The symmetrical grain size makes metering a breeze in powder measures. The burning rate of the 3N37 is close to N350 and on the medium scale of Vihtavuoris handgun powders. This is an excellent powder for 9 mm major loads for IPSC open competitions and its very popular in USPSA and IPSC practical pistol shooting disciplines. In addition to practical shooting, 3N37 is also widely used as a submachine gun powder. As all of Vihtavuoris powders, 3N37 offers consistent, extreme precision, with clean burning - and that is why it is used by the best shooters in the world. Interesting fact: 3N37 was used back in the 1940s by Sako for loading 9mm submachine gun cartridges.
