Vihtavuori N150 Smokeless Gun Powder: Multipurpose Rifle Powder for .30-06, .308 Win & 6.5×55

Vihtavuori N150 is one of Vihtavuori’s most popular N100-series rifle powders, prized by reloaders as a genuine all-rounder for European and North American hunting and target cartridges alike. It’s a favorite go-to for mid-case-capacity rifle rounds loaded with heavier bullets.

Built for All-Around Versatility

N150 uses a tubular grain measuring 1.3mm long and 1.1mm in diameter, a nearly symmetrical shape that feeds consistently through reloading equipment. On Vihtavuori’s own N100-series burn-rate chart, N150 sits on the medium scale, positioned between the faster-burning N140 and the slower-burning N160. N150 is also one of Vihtavuori’s most temperature-insensitive powders, and its added decoppering agent keeps copper fouling minor even with copper-jacketed bullets. Vihtavuori’s production process controls the full chain from nitrocellulose manufacture to final bottling, giving the lot-to-lot consistency reloaders need for repeatable results.

Application Versatility

N150 has official published load data for an unusually wide range of cartridges — including .223 Remington, 6mm Creedmoor, 6.5 Creedmoor, 6.5×55 Swedish Mauser, .270 Winchester, 7mm-08 Remington, .308 Winchester, .30-06 Springfield, .300 Winchester Magnum, and dozens more across 47 total published cartridges. Vihtavuori positions it as one of the best all-rounder choices for European hunting calibers, especially with heavier bullets in accuracy and hunting loads. If you need a slightly faster-burning N100-series option, Vihtavuori N140 is worth comparing.

Load Development

Always use published, manufacturer-tested load data when developing loads with N150. 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.
