Vihtavuori N550 Rifle Powder was originally developed for .30-06 Springfield and .308 Win. calibers in the late 90’s. In addition, Vihtavuori’s N550 high energy powder is a slower burning powder. It is very well suited to reloading a wide range of medium to large cartridges. This is especially true with heavier bullet weights.

The N550 is an ideal fit for many of the 30 caliber magnums with lighter bullets. However, it is 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. Additionally, it works 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. So, as with all of our N500 series powders, nitroglycerine has been added to the traditional single base powder. This is done 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. Importantly, higher velocity is acquired with equal pressure compared to the N100 series. This happens without increased wear on the rifle!

What are smokeless powders?

Smokeless powders, or propellants, are essentially mixtures of chemicals. So, they are designed to burn under controlled conditions at the proper rate to fire a projectile from a firearm. Smokeless powders are made in three forms:

• Thin, circular flakes or wafers
• Small cylinders
• Small spheres

Single-base smokeless powders derive their main source of energy from nitrocellulose. On the other hand, the energy released from double-base smokeless powders (such as the Vihtavuori N500 rifle powders) is derived from both nitrocellulose and nitroglycerine.
