So I'm loading 156 grain norma oryx and Alaskans in my 26" barreled 6.5-06. Using H1000 last night, the max load, according to hodgdon is 55 grains, which should yield 2680 fps. I loaded up 3 rounds with 54.0 grains, and seated to 3.275", which is .025" off the lands. This yielded me an average of 2830 fps, with an ES of 20 fps and SD of 11.41. I drop one grain to 53.0 grains, and my velocity drops to 2540 fps. ES is in the high 40's, and SD is in the 20's. So, my question is this. Does this sound normal, or perhaps does this sound like a chrony malfunction?
