Vihtavuori N565 Smokeless Gun Powder

A perfectly matched powder from the R&D team at Vihtavuori. Thanks to input and requests from customers, Vihtavuori is pleased to introduce the latest addition to the 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 grain bullets.

In addition to a precisely tailored burn rate, this powder is extremely temperature stable, giving uniform results across a wide range of environments. Vihtavuori also incorporated improved hygroscopic stability and a 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 Mag.

Designed for Magnum and High-Performance Cartridges

Vihtavuori N565 Smokeless Gun Powder is the top choice for reloaders seeking superior consistency, temperature stability, and accuracy in magnum-class cartridges. Specially engineered for popular long-range rounds like .338 Lapua Magnum, .300 Winchester Magnum, and 6.5 PRC, N565 bridges the performance gap between N560 and N570, delivering impressive velocity with remarkable shot-to-shot precision. Whether you’re pushing heavy bullets for distance or fine-tuning a hunting load, N565 ensures confidence at every pull of the trigger.

Exceptional Temperature Stability and Consistency

Built with Vihtavuori’s unmatched manufacturing precision, N565 offers temperature-insensitive burn characteristics, maintaining predictable performance across hot and cold environments alike. This feature is crucial for competitive shooters and hunters who demand consistent pressures, velocities, and accuracy from one session to the next. Its advanced chemistry keeps your ballistic performance stable, no matter the conditions.

Clean-Burning, Smooth Metering Performance

N565’s spherical grain design ensures smooth metering through all types of powder measures, helping you achieve repeatable charges and efficient load development. It burns cleanly, leaving minimal residue in your barrel extending maintenance intervals and enhancing overall firearm longevity. With less fouling and more shooting, Vihtavuori N565 gives reloaders the precision they crave and the reliability they can trust.
