A perfectly matched powder from our R&D team at Vihtavuori. Thanks to input and requests from our customers, Vihtavuori is pleased to introduce the latest addition to our N500 series of High Energy powders; the N565.

Designed to fill the gap between Vihtavuori N560 and N570 high energy rifle powders, the N565 was created specifically for the .338 Lapua Magnum with 250 gr bullets. In addition to a precisely tailored burn rate, this powder is extremely temperature stable, giving uniform results across a wide range of environments. We’ve also incorporated improved hygroscopic stability and our new decoppering agent to ensure a cleaner barrel when shooting. N565 is also REACH compliant without DNT or phthalates.

Physically, N565 grains have the same size as those of the N560 powder. As all Vihtavuori powders, it flows smoothly through powder measures and ensures good loadability and uniformity. The burn rate of the powder is a bit closer to N570, roughly splitting the difference between the two. Vihtavuori N565 is a single perforated extruded powder, having a bulk density of 960 g/l and an energy content of 4000 J/g.

While N565 was developed specifically for military sniping applications, it also has a wide range of sporting uses, particularly within long range shooting. The N565 will prove to be an ideal choice for calibers such as the 7mm Rem. Magnum, the .30-06, .300 Win Mag, .300 Norma Mag as well as the .338 Norma Magnum.
