Vihtavuori's N150 multipurpose rifle powder is one of our 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. The N150 is one of, if not the best, all-rounder powder for European hunting calibers. N150 is a tubular powder type with grain dimensions of 1,3 mm length and 1,1 mm diameter and the nearly symmetrical shape makes it a good companion for all kinds of reloading equipment. The burn rate of the N150 is on the medium scale of our rifle powders. It is also one of our most temperature insensitive powders, and thanks to the added decoppering agent, the coppering of the rifle barrel is minor even when using copper bullets.
