The top competitive shooters and manufacturers use Vihtavuori Smokeless Powder, which has a great reputation. These powders burn cleanly and shoot reliably in all weather. Vihtavuori Smokeless Powders have excellent quality since they control the entire manufacturing chain from nitrocellulose production to bottling. These tight quality acceptance limitations have helped reloaders and cartridge makers obtain identical loads independent of production lot for over 85 years. It’s clear why elite shooters worldwide prefer Vihtavuori Smokeless Powders.
The handgun powders in the N300 family are single-base porous powders. N340, formerly known as 3N18, is a genuine multipurpose powder that has its origins in 9mm and shotshell loads. Popular among the Vihtavuori N300 series of powders, this pistol powder is adaptable to a wide range of cartridge sizes and bullet weights, making it an ideal reloading companion.
The N340 powder is ideal for medium and heavy loads, including those used in handguns of medium and large calibers, as well as shotshells of medium and large calibers. N340 powder is a tubular powder with 1.0 mm long grains and 0.8 mm wide particles. All three powders (N320, N330, and N350) have the same particle size, however their porosities vary. Vihtavuori N340 has a moderate burn time compared to other Vihtavuori handgun powders, and like N320, it burns completely cleanly and leaves behind no residue.
Other Crucial Information:
Do not go above the loads listed in the reloaders guide.
Mixing two powders, regardless of type, brand, or source, is never a good idea.
Never substitute any smokeless powder for black powder or any substitute for black powder.
