41st edition of Lyman reloading handbook has the .38 Spec. High Vel. data. The loads using 2400 ( old formula stuff ) are quite impressive. Give same results as their moderate .357 loads.
As previously stated......NEVER start with max or near max loads. Pressures will vary from gun to gun, case brand differences etc etc.
Sam.....my favorite 9mm is the 9X32R
