Vihtavuori N310, known as N14 back in the old days, is a single-base, tubular powder type with grain dimensions of 0,7 mm length and 0,6 mm diameter. Thanks to its small size and almost symmetrical grain size, the powder flows smoothly and meters well in reloading measures. As with our other N300 series powders, N310 is a porous powder, in fact one of our most porous powder types. Porosity is a key factor influencing burning characteristics of powders; the more porous the powder, the faster the achieved burning rate.
Vihtavuori N310 is often used for light target loads, paired with light bullets, but it also works with heavier bullets. As a very versatile powder, it is suitable also for loading shotshells and is in fact used by shotgun ammunition manufacturers in their premium cartridges with light 24 gram target loads. The N310 is also used by many blank ammunition manufacturers.
