to Berry's 147gr RN. Am I going to need to adjust my load? Currently using 3.7gr of W231, OAL of 1.115. Will they chrono the same using that load as the Ranier? Or am I going to have to develop the load again?

I'd probably back it off 3/10 or 4/10 to start with since you're changing bullets. In reality there will most likely be no noticeable difference, but you never know. Don't forget to compare bullet lengths.
