New to the board , But i will chime in here. I load 9mm for the wifes CZ-75bd and .40 for my Glock 23. I've been using AA#5 for both. The 9 is 124 grn bullet with the 40 running a 165 grn. I get my bullets from Precuision delta. Both load are for plinking. Still working on a good load for the 9. My 40 runs 7 grns aa#5 with fed 100 primers in fed brass OAL at 1.124-1.127. Still have all fingers yet. This load is close to Max, so work up to it. My books ready 7.2 max load!!!!
