I am looking for load data and your experiences with magpro powder in the 300 Win Mag. The Accurate website says magpro is a good powder for the 300 Win Mag, but does not list any load data for it. What are everyone's loads and experience with this powder? I have been using h1000 and retumbo, just wondering if I could expect to gain some velocity and accuracy with the magpro. Thanks guys.
