Per Spclment I do the exact same thing with the 147 Smiley bullets. I use the Lee Modern Loading data for 146 gr 38 Spcl just as he stated above. In the same book under 9mm there is load data for 147 gr bullets I am going to try next. I don’t see why there would be any difference except pressure depending on bullet depth. As long as I’m within specs I feel it should work fine. Unless someone else knows something I don’t 🙂
