I decided to try some H4350 in my 6.5 x 47 today since I had read so much about how good it shot. I started at 41.0 grains and loaded 3 rounds at 41.0, 41.5 and 42 grains. Although you can’t get the velocity of RL 15 the accuracy was great. At 720 yards the 41.0 group was only 2 1/4 inches with about 1 1/2 inches of vertical. The second group also was only 2 1/4 inches with even less vertical. At 42 grains the group went vertical but was still just 3 inches. Tomorrow I plan to shoot through chrony and see what the velocity is but I’m expecting 2850 Fps. Is anybody else using this powder in a 6.5 and getting good results?
