[QUOTE="rufous, post: 21620, member: 122"] I went out again this afternoon. It was not nearly as foggy. I set the target up at 200 yards at tried the 73 grains of RL25 load again that gave me a 0.31" group at 65 yards. It was 1.78". Then I tried 74.0 grains and got 1.25". 74.5 gave 0.5" and 75.0 gave 0.74". Looks like 74.5 grains is my load. I hope to try it tomorrow at longer ranges. I have not yet started fiddling with seating depth. I just have it touching the lands, but if I can duplicate that 1/2" group at 200 yards I probably will just go with that. I do not know what the velocity is but am guessing it is in the 2750 to 2800 fps range. Rufous. [/QUOTE]
