I load 4.7grs of W231 for +P 158gr Speer LSWCHP and LSWC bullets, Winchester case and WSP primers. These are pretty much right at Winchesters factory +P 158gr LSWCHP velocity (890fps) from a 4" barrel with a chrono'd average or 892 fps from my S&W 67.

For general shooting at paper I usually load 4.3 to 4.5grs with 158gr RN and SWC lead and 3.1grs with 148gr HBWC's.
