Accurate MAGPRO is a slow burning, double-base, spherical rifle powder developed specifically for the Short magnums of both Winchester (WSM) and Remington (SAUM). This powder excels in the 6.5 x 284, 270 WSM and the 7mm WSM. MAGPRO is an excellent choice for belted cartridges such as the 300 Win Mag. Consistent performance can be expected from the excellent metering properties of MAGPRO.
