OK a NOOB to .40sw reloading. As it is a high presser load I am ensuring that I am doing my due diligance. The Lee loading data has min load at (165 grain TMJFN) 6.2 grns, speer manual has it at 7.6 grns, and accurates load data has it at 7.2. This is a huge variance. As the min for the second 2 sources exceeds the max load data provided by Lee. What I am trying to achieve is a lower pressure load for range and IDPA. Anyone with some experience with this powder your advise is appreciated. Currently I am thinking starting at the lowest min load data and adjusting from there, but I always appreciate advice form the been there done that crowd.
