Accurate

Accurate's Magpro is a slow-burning, double-base, spherical rifle powder developed specifically for the short magnums of both Winchester (WSM) and Remington (SAUM). This smokeless powder excels in the 6.5x284, 270 WSM and the 7mm WSM. Consistent performance can be expected from the excellent metering properties of Magpro, and it was designed to produce optimum velocities at nearly full case capacity in these "modern" calibers. Magpro is an excellent choice for belted cartridges such as the 300 Win Mag. Magpro makes long range hunting as efficient as the caliber for which it was designed. Made in the USA.
