I took the 180s up to 62.5 gr RL25 without pressure signs in Remington brass. Since I loaded those rounds my Nosler brass came in. It is 15 gr heavier than the Remington. It will also hold 1.5 gr more of ball powder.Since I will likely need to start over completely, I can change primers without problem.
You say the Nosler brass weighs 15 gr more than the RP and yet it still holds 1.5 gr more powder? That is not usually possible, at least from what I have read. Is that a Nosler case that has been fired and FL resized with the same die that you used to FL resize the RP brass?
Got to be careful to compare apples to apples. As you note, starting over is pretty much the way to go, regardless it its accuracy or speed you are looking for. Each needs to be brought up with the same line of cases, preferrably lot and weight too.....
