Vihtavuori n565 smokeless powder in stock

Smokeless powder in stock, it consists of nitrocellulose (single-base powders), frequently combined with up to 50 percent nitroglycerin (double-base powders), and sometimes nitroglycerin and nitroguanidine (triple-base), corned into small spherical balls or extruded into cylinders or flakes using solvents such as ether.

Other minor ingredients, such as stabilizers and ballistic modifiers, are also added. Double-base propellants are common in handgun and rifle ammunition. Triple-base propellants are more common in artillery guns.

Reasons for smokeless

The reason that they are smokeless is that the combustion products are mainly gaseous, compared to around 55% solid products for black powder (potassium carbonate, potassium sulfate etc).
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.
