The Vihtavuori N550 is a high-energy, medium burn rate rifle powder ideal for a wide range of calibers, offering enhanced velocity and consistent performance for hunting and target shooting applications.
Vihtavuori's N550 rifle powder was originally developed in the late 1990s for .30-06 Springfield and .308 Winchester calibers. It has since proven to be an excellent choice for many 30 caliber magnums with lighter bullets and is also suitable for other powerful loads such as 6.5×55 SE and .308 Winchester. The N550 is a tubular powder with symmetrical grain dimensions of 1.0 mm in length and 1.0 mm in diameter. As with all N500 series powders, nitroglycerine has been added to the traditional single-base powder to achieve better energy content. The burning rate of N550 is similar to that of the N150 rifle powder, placing it on the medium scale of Vihtavuori's high-energy powders. This composition allows for higher velocities with equal pressure compared to the N100 series, without increased wear on the rifle.
