Vihtavuori’s 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 their other handgun powders.

This is an excellent powder for 9 mm major loads for IPSC open competitions and it’s 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. 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 1940’s by Sako for loading 9mm submachine gun cartridges.

Try 3N37 / 0,4 g (6,2 gr) with a 9mm 8 g (124 gr) FMJ or HP bullet – a guaranteed recipe for success in IPSC open divisions!

Clean Burning: Vihtavuori uses only the finest of raw materials and take great pride in producing a very pure and clean burning powder which allows longer shooting sessions between cleanings. The clean-burning characteristics of our powders result in greatly reduced carbon build-up and powder fouling, ultimately giving longer barrel life.

Includes a Decoppering Agent:  After extensive testing and development, Vihtavuori has begun adding a decoppering agent to all powders. This additive deters the adhesion and build-up of copper fouling in the bore. Excessive jacket material fouling is a well-known and established cause of accuracy loss. This fouling must be removed from time to time to keep a rifle performing at its peak potential. The new decoppering agent prevents much of this fouling from building up in the first place, greatly prolonging your shooting sessions, and extending barrel life.

Temperature Stable: Temperature stability in powders has always been a consideration, but with the recent improvements in Long Range shooting, it has become a factor of major concern to shooters. Firing at long ranges places greater demands on ammo, equipment and the shooter himself. Enabling a shooter to meet these demands means refining the process, and eliminating those variables which reduce hit probability. The production of increasingly temperature insensitive propellants allows for greatly reduced Extreme Spreads and Standard Deviation, which translates directly to less vertical dispersion on target.

Consistency: Smokeless propellants are an organic compound of many closely monitored base materials. Every production run must be closely matched to very specific standards regarding grain geometry, chemistry and performance as compared to previous runs of that powder. This demanding process requires constant testing, verification and adjustment to ensure that each run is perfectly compatible with those before and after.

N300/3N: offers porous single base gun powders and precise measuring capability for pistol cartridges, rimfire ammunition and shotgun shells.

The estimated shelf-life of Vihtavuori gun powders is a minimum of 10 years, if stored and sealed in its original containers at a temperature circa 20°C and relative humidity of circa 55 %.
