N320 porous handgun and shotgun powder

The N320, formerly known as 3N22, is a fast burning, porous handgun powder. N320 is one of our most popular handgun powders and can be used for a wide range of pistol calibers from .32 to .45. It is most commonly used by sport and hobby shooters such as Cowboy Action shooters, but as a very reliable gun powder it is also suitable for authority applications. The powder type is tubular, with grain dimensions 1,1 mm x 0,8 mm (length x diameter), and as all our reloading powders it includes the added decoppering agent.

Cowboy Action Shooter “Evil Roy” vouches for the purity of Vihtavuori N320

As an extremely clean burning and accurate powder, N320 is also a big favorite of Gene Pearcey aka “Evil Roy”, the famous Cowboy Action Shooter using

Vihtavuori Powders. Speaking to Vihtavuori at the SHOT Show in Las Vegas in 2017, Evil Roy concluded:

“I’ve been using the N320 powder for quite a long time now, and it’s definitely my favourite powder. I use it for .45 ACP, .45 Colt, 9 mm and .38 Special, so I use it for a lot of things. And it just occurred to me some time ago, that I have been using that powder for years, and I haven’t cleaned my powder measure one time – not one single time.”
