I load 125 gr Berry's or Rainier plated 357's with ww brass, wsp primer and 8.0 gr of 231/hp38. Nice mild target load out of my GP 100. Speer # 13 lists starting load at 7.7 gr, max at 8.3 gr. This gives me a sweet load that is in between the 38 sp +p and a magnum load. Speer manual says it should do around 1100 fps.
