Vihtavuori 20N29 Rifle Powder

Vihtavuori rifle powder was originally developed for .50 BMG and military use, with the name 20N29 originating from Finnish Army standards.

20N29 is a single-based, surface-treated powder with grain dimensions of 23 mm in length and 13 mm in diameter. Its slower burning rate and larger grain size distinguish it from N100 series powders, making it well suited for large-caliber and magnum applications using heavy bullets, as well as long-range target shooting.

Ideally suited for .50 BMG, this large-caliber rifle powder has also earned a strong reputation in cartridges such as .300 Lapua Magnum and .30-378 Weatherby Magnum.
