Vihtavuori N310 Smokeless Gun Powder For Sale. The powders of the N300 series are single-base porous handgun powders. Previously known as N14, Vihtavuori N310 is a single-base, tubular powder with grain size of 0.7 mm in length and 0.6 mm in diameter. Due to its compact size and almost symmetrical grain size, the powder flows easily and measures accurately for reloading. N310, like other powders in the N300 family, is a porous powder. Porosity is a significant component in determining the burning properties of powders; the more porous the powder, the quicker the burning rate attained. Vihtavuori N310 is often used with low target loads and bullets, although it is also compatible with larger rounds. As a very adaptable powder, it is also ideal for loading shotshells, and shotgun ammunition makers utilize it in their premium cartridges with 24 gram target loads. The N310 is also used by several makers of blank ammo.

Other Important Information:

• Do not exceed the loads displayed in the reloaders guide.
• Never mix any two powders regardless of type, brand, or source.
