Vihtavuori N310 Smokeless Gun Powder: Fast-Burning Pistol Powder for Light Target Loads

Vihtavuori N310 (known as N14 in earlier years) is the fastest-burning powder in Vihtavuori’s N300 series, purpose-built for light target loads in Bullseye-style competitive pistol shooting and other precision handgun disciplines.

Built for Fast, Clean Target Loads

N310 uses a small, nearly symmetrical tubular grain measuring 0.7mm long and 0.6mm in diameter. Like the rest of the N300 series, it’s a porous powder — porosity is what drives its fast burn rate, and N310 is one of the most porous types Vihtavuori makes. On Vihtavuori’s own N300-series burn-rate chart, N310 sits at the very fast end, just ahead of Vihtavuori N320. Vihtavuori’s production process controls the full chain from nitrocellulose manufacture to final bottling, giving the lot-to-lot consistency competitive shooters need for repeatable scores.

Application Versatility

N310 has official published load data for light target loads in .32 S&W Long (including wadcutter loads), 9mm Browning Court/.380 Auto, 9mm Luger, .38 Special, and .45 ACP, and is a long-time favorite for competitive Bullseye pistol shooting. It’s also versatile enough for use with heavier bullets, and Vihtavuori rates it for target shotshell loads (including premium 24-gram loads) and for blank ammunition manufacturing. If you need a slightly slower-burning N300-series option, Vihtavuori N320 is worth comparing.

Load Development

Always use published, manufacturer-tested load data when developing loads with N310. 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.
