About this powder
N320 is Vihtavuori's premium fast pistol powder, favored by IPSC and IDPA competitors for its exceptionally consistent velocity and near-zero muzzle flash. Works across 9mm, .38 Spl, and .45 ACP. Finnish competitive shooters rely on it for minor power factor loads with minimum charge weights.
