I could be wrong, but I don't read it like he's expecting the same velocity from different powders. I think he's getting velocity variance with the same load of the same powder. He just gets the same wide variance regardless of the powder he used. Is that right, Robert?
Mixed brass, or is it all from the same lot? Full length sizing or neck sizing?
Do you have enough neck tension that you can't push the bullet into the case any farther by pressing the tip against your workbench withot trying really hard?
