I am reloading 9mm with lead bullets for a friend. I haven't reloaded lead in a long time. The 9mm bullets are 123.5 grain in weight. I can't find any information on how much Winchester 231 powder to load with that grain bullet. The best I could find was for 115 grain lead and 147 grain lead with that powder. Does anyone have any loading data for that grain lead bullet? Thanks.
