If you prepared the new brass (Sized,trimmed and deburred) just re size with the same setting.
If you didn't prep then I would prep before the first reloading and the fact that the brass now
fits your chamber I would ether neck size only or full length size just enough to make them
chamber well. (This will make the brass last longer if not worked to hard).
