Vihtavuori N570 rifle powder

It’s time to talk heavy powders again!

Vihtavuori's N570 rifle powder is the youngest member in our high-energy powder family. It was developed at the request of magnum cartridge reloaders roughly a decade ago. We realized that this kind of powder was desired yet lacking on the market, so we decided to develop N570 to meet our customers' needs.

The characteristics of this high energy powder with its large grain size and high bulk density are developed to bring out the maximum velocities of cartridges with very large volume cases like the 6,5-.284 Norma, the .300 Winchester Magnum, the .300 Remington Ultra Magnum and the .338 Lapua Magnum.

Vihtavuori N570 is mainly used in long-range target shooting and in military applications with big volume cartridges.

N570 is the slowest of our high-energy powders and is an extruded, tubular powder type with grain dimensions of 2,3 mm length and 1,3 mm diameter. Due to the large kernel size (similar to 24N41 and 20N29), we recommend you to always weigh your N570 charges rather than relying on throws from powder measures, as they do not always deliver consistent charges. This way you can avoid under or over-charging cases.

Like all of our N500 series rifle powders, the N570 is manufactured from our own high-quality nitro-cellulose with grains impregnated with nitroglycerine and non-energetic additives. The result: increased muzzle velocity without increased chamber pressure and without increased wear on the gun!
