Vihtavuori N150 Smokeless Powder - 1lb Can - Vihtavuori's N150 multipurpose rifle powder is one of their most popular reloading products. It is commonly used with heavier bullets in accuracy loads and hunting loads in cartridges with middle case volumes, like the .30-06 Springfield, the .308 Winchester, and the 6,5A-55 SE. N150 is a tubular powder type with grain dimensions of 1,3 mm length and 1,1 mm diameter. The nearly symmetrical shape makes it a good companion for all kinds of reloading equipment. The burn rate is on the medium scale of Vihtavuori's rifle powders. It is also one of Vihtavuori's most temperature insensitive powders, and thanks to the added decoppering agent, the coppering of the rifle barrel is minor even when using copper bullets.
