The top competitive shooters and manufacturers use Vihtavuori Smokeless Powder, which has a great reputation. These powders burn cleanly and shoot reliably in all weather. Vihtavuori Smokeless Powders have excellent quality since they control the entire manufacturing chain from nitrocellulose production to bottling. These tight quality acceptance limitations have helped reloaders and cartridge makers obtain identical loads independent of production lot for over 85 years. It’s clear why elite shooters worldwide prefer Vihtavuori Smokeless Powders.

Nitroglycerol-impregnated rifle powders are the N500 series. N500 series powders can replace N100 series powders for better loading densities and energy. In the late 1990s, Vihtavuori created N550 rifle powder for.30-06 Springfield and.308 Win. The N550 powder works well with numerous 30 caliber magnums with lighter bullets and a wide range of barrel sizes in various shooting disciplines.

It works well for.30-06 Springfield hunting rounds with larger bullets, 6,5×55 SE,.308 Winchester, and others. Tubular N550 powder has symmetrical grain size of 1 mm length and 1 mm diameter. To boost energy, nitroglycerine is added to the traditional single base powder in all N500 series powders. N550 burns like N150 rifle powder, a medium-energy powder. With equal pressure, the N100 series achieves more velocity without rifle wear!
