Vihtavuori N320 Smokeless Handgun Powder — EQV. TO APS450

Vihtavuori N320 is one of the world's most popular handgun reloading powders, trusted by competitive shooters and handloaders for its outstanding accuracy, exceptionally clean-burning performance and remarkable versatility. Formerly known as 3N22 , this premium single-base smokeless powder is ideal for light to mid-range target loads across a broad range of handgun calibres, making it a favourite for IPSC, ISSF, Cowboy Action and general target shooting.

Manufactured in Finland to Vihtavuori's exacting standards, N320 features a fast-burning, porous tubular grain that meters consistently through powder measures while producing reliable velocities and excellent shot-to-shot uniformity. Compared with N310, N320 offers greater versatility and is capable of achieving higher velocities at acceptable pressures, making it an excellent all-round choice for both recreational and competition handloading.
