Vihtavuori N530 1lb Gun Powder 1.4C, UN0509

This is the fastest burning reloading powder in the N500 series and its burning rate is close to Vihtavuori N135 and Hodgdon BL-C(2). Developed especially for the 5,56 mm NATO-cartridges and it gives excellent performances in many .45-70 Government loads and also in .308 Winchester loads with bullet weight less than 10 grams (155 grains).
