N105 Super Magnum is VihtaVuori’s slowest burning pistol powder, intended for the most powerful handgun cartridges in use today, particularly with heavy bullets and/or large case volume. Many of these specialized rounds operate at rifle pressures. Delivering this type of performance is precisely what prompted the development of N105. For such powerhouses as the .54 Casull or 500 S&W, N105 is an excellent powder choice. Mfg: Vihtavuori
