[QUOTE="MagnumManiac, post: 1625248, member: 10755"] 3 powders work for me in 3 hunting rifles and 3 target barrels. RE25 gets the highest velocities and very good groups for me with 180-200gr bullets. RETUMBO gets the highest velocities with 210-230's and H1000 gets lower velocities but the best accuracy for my target shooting, closely followed by RETUMBO. This is not to say RE25 is the worst for accuracy, in fact it gives the best accuracy with 180gr Accubonds in 2 of my 300's. Supreme 780 is also a very good powder, this is what is in factory Winchester ammo, albeit a blended version known as 785. As to accuracy, have you done a seating depth test yet? If not, thus may be your issue, you haven't found the 'sweet spot for your bullet. Go to the Berger site and follow their seating depth test. All the best with it. The 300WM is one of the most accurate rounds out there, you WILL find a load that shoots tiny groups. Cheers. [/QUOTE]
