[QUOTE="Greyfox, post: 1400407, member: 10291"] I have seen choice of powder make a difference for a given velocity. Not sure whether it’s due to burn characteristics, effect on barrel harmonics, etc. I exactly matched the velocity in one of my 6.5x284’s of 2970FPS using 57gr of Retumbo and 54gr of Reloader 26. Both used with Lapua Brass, Fed210M, Berger 140HVLD at the same seating depth, same day. Velocity and ES were the same, however in my rifle, Retumbo which has.and continues to produce sub .5MOA groups is noticably better then Reloader 26 which was .75MOA, best case. Reloader 26 may very well have a different accuracy node which I haven’t explored yet. [/QUOTE]
