Vihtavuori N560 is a very slow-burning powder for large, Magnum-style cases, particularly when heavy bullets and high velocities are required. It is well-suited for handloaders preferring calibers such as the .270 Win, 7 mm Remington or 7 mm Weatherby Magnum, .300 Winchester, RUM or Weatherby Magnum. This rifle powder is also a very good choice for the .338 Lapua Magnum when using lighter bullets of 250 grains or less.
