Vihtavuori N550 Powder 8 lb Canister

Vihtavuori N550 Rifle Powder - 8lb

Originally developed for .30-06 Springfield and .308 Winchester, Vihtavuori N550 is a powerhouse performer for shooters who demand both flexibility and performance. Ideal for 30-caliber magnums with lighter bullets, N550 also shines in heavy .30-06 loads, potent 6.5x55 SE setups, and a broad range of other applications.

With a symmetrical tubular grain shape (1.0 mm x 1.0 mm), N550 flows smoothly through reloading equipment for easy, consistent metering. As part of the high-energy N500 series, it’s enhanced with nitroglycerine for improved velocity and energy—while maintaining pressures comparable to N100 series powders. That means more speed without added stress on your rifle.

Sitting at a medium burn rate, similar to N150, N550 gives you dependable performance across disciplines.
