The N500 series of Vihtavuori propellants provide the utmost in performance for added velocity and range with heavy bullets. Nitroglycerine has been added to the traditional single base rifle powder to get better energy content. The series offers six different reloading powders with different burning rates, suitable for a variety of shooting disciplines such as long range target shooting.
N530 HIGH ENERGY POWDER
The fastest of Vihtavuori's N500 High Energy series, the N530 is an ideal reloading powder for many of the smaller bottlenecked cases like the .223/5.56, or large straight-walled cases such as the .45-70 Springfield. It is also a useful powder for medium capacity cases like the .308 Winchester when using lighter weight bullets of 155 grains or less.
N540 HIGH ENERGY POWDER
Vihtavuori N540 is a mid-range powder in the N500 series, and an excellent choice for cartridges running from the .223/5.56mm, .308 Win. and .30-06 Springfield with appropriate bullet weights. This is also a great powder for 6,5x47 Lapua and 6.5 Creedmoor as well as the .223 when using heavy bullets from 69 to 82 grains. It is exceptionally clean-burning and delivers outstanding accuracy.
N550 HIGH ENERGY POWDER
Vihtavuori's N550 high energy powder is a slower burning powder, very well suited to reloading a wide range of medium to large cartridges especially with heavier bullet weights. The N550 is an ideal fit for many of the 30 caliber magnums with lighter bullets, but also useful across a wide range of bore sizes in various shooting disciplines. Particularly well matched to heavy bullet loadings in the 6.5x55 and .30-06 Springfield cartridges.
N560 HIGH ENERGY POWDER
Vihtavuori N560 is a very slow-burning powder for large, magnum-style cases, particularly when heavy bullets and high velocities are required. It is well-suited for handloaders preferring calibers such as the .270 Win, 7 mm Remington or 7 mm Weatherby Magnum, .300 Winchester, RUM or Weatherby Magnum. This rifle powder is also very good choice for the .338 Lapua Magnum when using lighter bullets of 250 grains or less.
N565 HIGH ENERGY POWDER
Vihtavuori's N565 is a new N500 series powder developed specially for 250 grain bullet weight loads in .338 Lapua Magnum. N565 roughly splits the difference in burn-rate between the powders N560 and N570, but is a bit closer to N570. It will cover many of the same calibers and bullets as the first two, but allows the loader another option in fine-tuning a load to the perfect combination. While N565 was tailored specifically for military sniping applications, it also has a wide range of sport shooting uses, particularly within long range shooting. For the demanding handloader, the N565 will prove to be an ideal choice for calibers such as the 7mm Remington Magnum, the .30-06, .300 Win Mag, .300 Norma Mag as well as the .338 Norma Mag.
N570 HIGH ENERGY POWDER
Vihtavuori N570 high energy powder is the slowest burning member of the N500 line and a perfect choice for shooting disciplines requiring heavy bullets and the largest capacity cases. Its burn rate is very close to that of Vihtavuori N170 rifle powder, but will generally provide a bit more velocity in the same cartridges using the same bullet weights. The burn-rate characteristics of N570 allow it to deliver the very best possible performance from such cartridges as the 6.5x284, .300 Rem. Ultra Mag, and .338 Lapua Magnum.

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. Manufacturing propellants entirely in-house ensures their high quality. All Vihtavuori powders are made using nitro-cellulose produced by cotton linters at our own plant. Vihtavuori rifle and pistol powders deliver consistently flawless firing performance – for you this means reliable reloading and ammunition you demand..
Vihtavuori premium reloading powders come in three different series:
N100 offers traditional single base propellants for rifle calibers, N300/3N offers porous single base gun powders and precise measuring capability for pistol cartridges, rimfire ammunition and shotgun shells, N500 series powders are special high energy rifle propellants enhanced with nitroglycerin for extra ballistic performance.
All are STANAG 4170 qualified and REACH compliant.
Why choose Vihtavuori powders for reloading?
⇒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 powders result in greatly reduced carbon build-up and powder fouling, ultimately giving longer barrel life.
⇒They come with a Decoppering agent
After extensive testing and development, we’ve begun adding a decoppering agent to all of our powders. This additive deters the adhesion and build-up of copper fouling in the bore. Excessive jacket material fouling is a well-known and established cause of accuracy loss. This fouling must be removed from time to time to keep a rifle performing at its peak potential. Our new decoppering agent prevents much of this 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 powders has always been a consideration, but with the recent improvements in Long Range 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 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.
