Vihtavuori N555 Smokeless Gun Powder: Unmatched Precision for 6.5 Creedmoor

Vihtavuori N555 is an N500-series precision rifle powder designed for cartridges with large case volume and comparatively small bullet diameters, delivering unprecedented performance in 6.5 Creedmoor.

Built for Precision Rifle Performance

N555 is an impregnated extruded rifle powder with nitroglycerol added as an extra energy component, giving it higher loading density and more energy than comparable N100-series powders. On Vihtavuori’s own combined burn-rate chart, N555 sits between Vihtavuori N550 and N160. It’s the most temperature stable reloading powder in its class, giving competitive shooters and hunters dependable performance in extreme weather conditions. Energy content is 3,700 J/g with a bulk density of 900 g/l. Like all Vihtavuori powders, N555 includes an anti-fouling agent that minimizes barrel fouling to extend the length of your competitive shooting stages, and its unmatched lot-to-lot consistency eliminates costly range time re-developing favorite loads.

Application Versatility

N555 is designed for precision rifle platforms chambered in cartridges such as 6mm Creedmoor, 6.5 Creedmoor, .284 Winchester, .260 Remington, and .30-06 Springfield, and generally for rifle calibers with large case volume and comparatively small bullet diameters. It features unprecedented performance in 6.5 Creedmoor specifically, making it a top choice for PRS and long-range precision shooters. If you need a slightly faster-burning N500-series option, Vihtavuori N550 is worth comparing.

Load Development

Always use published, manufacturer-tested load data when developing loads with N555. 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.
