Vihtavuori N565 Smokeless Gun Powder: High-Energy Magnum Powder for Heavy Bullets

Vihtavuori N565 is an N500-series high-energy rifle powder developed to fill the gap between N560 and N570, created specifically for the .338 Lapua Magnum loaded with 250-grain bullets and other large-capacity magnum cartridges.

Built for Magnum Precision

N565 is a single-perforated extruded (tubular) powder impregnated with nitroglycerine for extra energy, giving it an energy content of 4,000 J/g and a bulk density of 960 g/l. It shares the same grain size as its sibling Vihtavuori N560, at roughly 1.4mm x 1.2mm. On Vihtavuori’s own combined burn-rate chart, N565 sits between N560 and N568, leaning slightly closer to the slower-burning N568/N570 end of that range. Like the rest of the Vihtavuori lineup, N565 includes a decoppering agent that helps keep the barrel cleaner across a shooting session, and its temperature-stable formulation holds consistent performance across a wide range of conditions.

Application Versatility

N565 was created specifically for the .338 Lapua Magnum with 250-grain bullets, and Vihtavuori also confirms it as an ideal choice for 7mm Remington Magnum, 7mm PRC, .30-06 Springfield, .300 Winchester Magnum, .300 PRC, .300 Norma Magnum, and .338 Norma Magnum, with additional official load data published for 6.5 PRC and 6.5 Creedmoor. N565 occupies a similar burn-rate range to Hodgdon H1000 on independent burn-rate charts, and some reloaders use it as a substitute when H1000 is hard to find — but the two are distinct powders, so always use load data published specifically for N565 rather than substituting H1000 charge weights. If you need a slightly faster-burning N500-series option, Vihtavuori N560 is worth comparing.

Load Development

Always use published, manufacturer-tested load data when developing loads with N565. 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.
