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).

N540

Faster burning powder with a burning rate like with N140 and close to Hodgdon H414 and Winchester 760. To situations where more power is needed, especially for .223 Remington, .308 Winchester and .30-06 Springfield loads with heavier bullets.

N550

N570

This is the newest member of the N500 series powders and also the slowest burning. The burning rate of N570 is near to N170 and it is faster burning than 24N41.
