N530 is also ideal for many smaller bottle-necked cases, including 223 Rem, 5.56mm and some large straight-walled cases like 45-70 Springfield.
Vihtavuori N530 Rifle Propellant was originally developed for 5.56mm x 45 in military use (NATO) but made a name for itself as a versatile powder for use in cartridges like 308 Win, 9.3 x 62, 45-70 Gov and 458 Win Mag.
