Formerly known as 3N18, the N340 is a true multipurpose gunpowder, developed originally for 9 mm and shotshell loads. This powder is one of the most popular gunpowders in the Vihtavuori N300 series, and it can be used for a wide variety of calibers and bullet weights, making it the perfect partner for all kinds of reloading purposes. The N340 is used especially for medium and large caliber pistols and shotshells with medium and heavy loads.
N340 is a tubular powder type with grain dimensions of 1,0mm length and 0,8 mm diameter. Exactly the same grain size as with powder N320, N330 and N350 – only the porosity of the powder changes. The burning rate of the N340 is at the medium scale of Vihtavuori handgun powders – and as with powder N320, with N340 extremely clean burning and no residuals is guaranteed.
…you’ve got to ask yourself one question: “Do I feel lucky?”
We think that even Dirty Harry himself possibly used Vihtavuori N350 in his famous .44 Rem Mag, when looking at his infallible shooting accuracy!
As the burning speed of N350 is at the slow end of our handgun powders, it is ideal for very heavy and top end velocities and energies for a broad range of pistol and revolver cartridges. N350 is widely used in pistol shooting and especially in practical shooting. N350 works excellent also in shotgun shooting with heavy hunting loads, especially with 36 gr loads or more. Saty tuned for shotgun reloading data in the future!
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 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.
Interesting fact: 3N37 was used back in the 1940’s by Sako for loading 9mm submachine gun cartridges.
