Vihtavuori N570 high energy powder is the slowest burning member of the N500 line and a perfect choice for shooting disciplines requiring heavy bullets and the largest capacity cases. Its burn rate is very close to that of Vihtavuori N170 rifle powder, but will generally provide a bit more velocity in the same cartridges using the same bullet weights. The burn-rate characteristics of N570 allow it to deliver the very best possible performance from such cartridges as the 6.5x284, .300 Rem. Ultra Mag, and .338 Lapua Magnum.
