[QUOTE="SSG Graybush, post: 1963283, member: 115190"] I found a good speed node at 63.7 to 64.2 of RL26 with a spread of only 12 fps. And I loaded 64.0 grs to test jumps. Loaded 5 rd sets at .065, .045, .030 and .015. .065 shot the best. 64.0 grs es of 7 and a sd of 3 at 2844 fps AV with .065 jump. Group was .75 for 4 shots in a vertical string and I pulled the last to 1 moa slightly left, maybe, could have been a flyer. Going to load .085, .095, .105 and .115 jumps for tomorrow. .115 should be about book coal. Today as my jump shortened the sd's went slightly up but not over 10 in any set and speed went slightly up as well with .015 jump having as sd of 10 at 2867 AV but group opened to 1.25. One thing I did notice today also was my scope is 1 slot too far forward, which is causing a cheek to stock weld issue, am stretching. If I cant get rid of the flyer I will continue up in charge weight, but I can live with 2844 fps with a sd of 3 if I can get the moa down below .625. Am curious what speeds you got at 68.5. Cuz I am wasnt close to any pressure signs at 64.5. [/QUOTE]
