Vihtavuori N550 Smokeless Gun Powder

Looking for Vihtavuori N550 in stock? Originally developed in the late 1990s for .30-06 Springfield and .308 Winchester, N550 is an impregnated extruded rifle powder from Vihtavuori’s N500 series, with nitroglycerine added to the traditional single-base formula for extra energy content. For safe charge weights, always consult Vihtavuori’s official load data before loading.

N550 is an ideal fit for many 30-caliber magnums loaded with lighter bullets, while also performing well across a wide range of bore sizes and shooting disciplines. It’s an excellent choice for .30-06 Springfield hunting rounds with heavier bullets, and equally capable in powerful loads for 6.5×55 SE, .308 Winchester, and more.

With symmetrical grain dimensions of 1.0mm length by 1.0mm diameter, N550 shares a similar burn rate to the N150 rifle powder, sitting on the medium scale of high-energy powders. Because it’s part of the N500 series, reloaders can achieve higher velocities at equal pressure compared to the N100 series — without extra wear on the rifle. If you’re loading .223 or smaller-capacity cartridges instead, Vihtavuori N540 may be the better match.
