Vihtavuori N540 powder

Vihtavuori N540 universal rifle powder

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.
