Vihtavuori N570 Smokeless Gun Powder: Ultra-Slow Burning High-Energy Magnum Powder

Vihtavuori N570 is the slowest-burning powder in Vihtavuori’s N500 High Energy series, built for today’s largest-capacity magnum cartridges and the heaviest bullets they push downrange.

Built for the Largest Magnum Cases

N570 is an extruded, tubular rifle powder impregnated with nitroglycerine for extra energy, with a large 2.3mm x 1.3mm grain size. On Vihtavuori’s own combined burn-rate chart, N570 is the slowest of the entire N500-series lineup, sitting just behind Vihtavuori N568. Because of its large grain size, Vihtavuori recommends weighing every charge rather than relying on a volumetric powder measure. Long-range shooters and magnum hunters favor N570 for its ability to fill large case capacities efficiently while maintaining the temperature stability and lot-to-lot consistency Vihtavuori is known for.

Application Versatility

N570 has official published load data for a wide range of large-capacity magnum cartridges, including .338 Lapua Magnum (notably with heavy 300-grain bullets), .300 PRC, .300 Norma Magnum, .300 Winchester Magnum, .300 Remington Ultra Magnum, 7mm PRC, 7mm Remington Ultra Magnum, .280 Remington, 6.5 PRC, 6.5-284 Norma, 6.8 Western, .375 CheyTac, and .50 BMG (listed in Vihtavuori’s own data as “.50 Browning”). If you need a slightly faster-burning N500-series option, Vihtavuori N568 is worth comparing.

Load Development

Always use published, manufacturer-tested load data when developing loads with N570. Start at the published minimum charge and work up in small increments, weigh every charge on a calibrated scale, and chronograph each string to track velocity consistency. Keep primer brand, bullet lot, and brass lot constant during development, watch for pressure signs, and document charge weight, seating depth, primer, and chronograph results so successful loads can be reproduced.

What cartridges is N570 best for? It has official published load data for .338 Lapua Magnum (especially with heavy 300-grain bullets), .300 PRC, .300 Norma Magnum, .300 Winchester Magnum, .300 RUM, 7mm PRC, .50 BMG, and other large-capacity magnum cartridges.
