Vihtavuori

Vihtavuori – the power of accuracy

For almost a hundred years, Vihtavuori powders have formed the heart of many of the world’s most renowned cartridges. Reloaders know they can trust in the performance and uniform high quality of Vihtavuori smokeless powders  – cartridge after cartridge – to create a perfect product for successful shooting. When choosing our reloading powder you know your ammo is up to the task, even in the toughest conditions. Go ahead, take Vihtavuori and make the perfect shot.

Why choose Vihtavuori powders for reloading?

Vihtavuori is known for producing high quality propellants with reliable ballistic performance, long shelf-life and wide variety selection. All of our gun powders meet the strict requirements of both civilian and military needs.

They’re Clean Burning

Our use of only the finest of raw materials is a renowned characteristic of all Vihtavuori powders. We take great pride in producing a very pure and clean burning powder which allows longer shooting sessions between cleanings. The clean-burning characteristics of our rifle and handgun powders result in greatly reduced carbon build-up and powder fouling, ultimately giving longer barrel life for rifles.

They come with a Decoppering agent

After extensive testing and development, we’ve begun adding a decoppering agent to all of our smokeless powders. This additive deters the adhesion and build-up of copper fouling in the bore, ie. the inside of the barrel of a firearm. Excessive jacket material fouling is a well-known and established cause of accuracy loss when shooting. The fouling must be removed from time to time to keep a rifle performing at its peak potential. Our new decoppering agent prevents much of barrel fouling from building up in the first place, greatly prolonging your shooting sessions, and extending barrel life.

They’re extremely temperature stable

Temperature stability in reloading powders has always been a consideration, but with the recent improvements in Long Range and ELR shooting, it has become a factor of major concern to shooters. Firing at long ranges places greater demands on ammo, equipment and the shooter himself. Enabling a shooter to meet these demands means refining the process, and eliminating those variables which reduce hit probability. The production of increasingly temperature insensitive propellants allows for greatly reduced Extreme Spreads and Standard Deviation, which translates directly to less vertical dispersion on target.

They’re lot-to-lot consistent

Smokeless propellants are an organic compound of many closely monitored base materials. Every production run of our smokeless powders must be closely matched to very specific standards regarding grain geometry, chemistry and performance as compared to previous runs of that powder. This demanding process requires constant testing, verification and adjustment to ensure that each run is perfectly compatible with those before and after. This is a guiding principle of our powder production philosophy. We require extreme accuracy and quality at every step of our production process.

Vihtavuori is experienced, quality craftsmanship for the perfect ammo

We manufacture our propellants entirely in-house, and this ensures their high quality. All our reloading powders are made using nitro-cellulose produced at our own plant. Vihtavuori rifle and pistol powders deliver consistently flawless firing performance – for you this means reliable reloading and ammunition you demand.

Each stage of the production process is subject to stringent quality control by our experts to ensure that each production lot has the exact ballistic performance required. Each and every batch produced is inspected by comparing them to selected reference batches.

All Vihtavuori powders for consumers are extruded propellants. Propellant grains are perforated cylinders of various sizes, flat ribbon flakes or other shapes extruded for special applications. The grain geometry of different gunpowder types provides the wanted combustion characteristics for the chosen cartridge application.

The estimated shelf-life of Vihtavuori gunpowders is a minimum of 10 years, if stored and sealed in its original containers at a temperature circa 20°C and relative humidity of circa 55 %.
