I just recently started loading 9mm and looking for some recipe ideas. I've tried 231 and Longshot powders so far with success "BUT", I'm noticing a big difference in loading data from my Lyman book showing a starting load of 231 for a 125gr jhp of 3.9gr to a max of 4.4gr. Hodgsons online reloading center shows a starting load of 231 at 4.4gr to a max of 4.8gr? This seems a bit out of wack any insight? Would won trust a online source or a $40 book?
