Vihtavuori N540 is a universal rifle powder for wide variety of medium-sized calibers suitable for both hunting and target shooting. It is an excellent choice for cartridges running from .223/5.56 mm to .308 Winchester and 30-06 Springfield with heavier bullet weights.
Vihtavuori N540 delivers outstanding accuracy with exceptionally clean burning. Due to the extra energy content that all of our N500 series powders include, a velocity up to 30-40 m/s higher can be achieved with the same pressure level compared to the equal in the N100 Vihtavuori series. It is certainly worth trying when using heavier bullets and when higher loading densities and muzzle velocities are needed!
Thanks to its symmetrical size (1,0 mm length and 1,0 mm diameter), N540 meters well in reloading equipment and makes loading super easy.
Vihtavuori’s N550 rifle powder was originally developed for .30-06 Springfield and .308 Win. calibers in the late 90’s. 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. It is an excellent powder for .30-06 Springfield hunting rounds with heavier bullets, and also for other more powerful loads of 6,5×55 SE, .308 Winchester plus many others.
The N550 is tubular powder type with symmetrical grain dimensions of 1,0 mm length and 1,0 mm diameter. As with all of our N500 series powders, nitroglycerine has been added to the traditional single base powder to get better energy content. The burning rate of N550 is similar to that of the N150 rifle powder and it’s on the medium scale of our high energy powders. Higher velocity is acquired with equal pressure compared to the N100 series – without increased wear on the rifle!
Vihtavuori’s N560 rifle powder is especially suitable to bring power to large and magnum calibers, for example .270 Winchester, 6,5-284, 7 mm Remington Magnum, 7 mm Weatherby Magnumand even the .416 Rigby. This rifle powder is also very good choice for handloading the .338 Lapua Magnum when using lighter bullets of 250 grains or less.
The N560 powder is a tubular type with a fairly large grain with dimensions of 1,4 mm length and 1,2 mm diameter. The burn rate of is slow on the scale of our rifle powders, between the N160 and N165. The N560 is similar to N100 series, but nitroglycerine has been added to it to get better energy content. The 500 series High Energy powders are mainly used in rifle cartridges where some extra energy content is needed to achieve bigger loading densities and higher muzzle velocities within the limits of maximum pressure. So, you get better velocity with the same pressure than with for instance the N165. The N560 is commonly used for big game hunting and sniper ammunition especially for larger caliber rifles. Especially in long distance hunting situations with reasonable calibers and bullets, the N560 magnum powder shows unbelievable performance.
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.
