[QUOTE="Jud96, post: 1837464, member: 69478"] That’s really not a terrible ES and SD to start with. I’ve found best results by finding a flat spot or “node” in my powder charge. I start a few grains below book max and work up one round at a time in .2 or .3 grain increments shooting each shot over the chronograph until I see pressure signs. Then I look over my data and there will be a window in your charges where loads that are .5gr or more different will have velocity numbers within a few FPS of one another. Then I load in the middle of those charge weights and go test 5-10 shots over the chronograph with that load and if the ES is under 20 I call it good. [/QUOTE]
