Your data for the 57.5gr H1000 is a very good match to the QuickLOAD prediction for your 25" barrel length, powder, bullet, CoL, and for the MV you recorded. This is helpful as it tends to indicate that QuickLOAD would continue to provide good predictions for your particular rifle as the variables are changed. By the way your peak pressure on that load is predicted as 59.2kPSI.
Whatever pressure signs you are seeing on the Norma cases are likely to show up again to the same degree at the same predicted peak pressure. We can use QuickLOAD then to predict what the other powders would deliver for the same peak pressure - other variables held constant: 2213sc-53.6gr-2920ft/sec, N560-54.6gr-3010ft/sec, Re-22-54.1gr-2985ft/sec.
Other than your H1000 load looking like it might be quite compressed, if you can fit it in the case OK then it looks to be the optimal ADI powder for the 6.5-06 + 140gr
Yes 3100ft/sec is predicted as achievable by QuickLOAD in a 25" barrel, but peak pressure must be increased to 65kPSI+, something your Norma cases might not appreciate.
