The main goal of reloading should be accuracy not speed. Speed is fine but accuracy is final. So what I am getting at are your current groups nice and tight as you were moving up in charge weight. Were they getting bigger or smaller.? If they are getting bigger I think you are past the sweet spot. With small primers in the Creedmoor I think you are going to show high pressure signs on your brass first and not necessarily on the primers. So be very careful.
