Vihtavuori 3N37 Smokeless Powder 2kg

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. Our 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.

3N37: This reloading powder was originally developed for .22 rimfire cartridges but has proven to be very versatile and desirable within all competitive handgun shooting disciplines. The burning speed of this small grain gun powder is near to N350 and Vectan A0. Reloading data available for all popular handgun cartridges.

  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 our 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. As all of our powders, 3N37 offers consistent, extreme precision, with clean burning – and that is why it is used by the best shooters in the world.

Other Important Information:

• Do not exceed the loads displayed in the reloaders guide.
• Never mix any two powders regardless of type, brand, or source.
• Never substitute any smokeless powder for Black Powder or any Black Powder substitute.

The estimated shelf-life of Vihtavuori gunpowders 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 %.
