Formerly known as 3N18, the N340 is a true multipurpose powder, developed originally for 9 mm and shotshell loads. This pistol powder is one of the most popular powders 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.
