I have been loading 38 special for a guy I met at the range and he is shooting them in a 357 mag revolver. I have just finished some 357 for him to test and boy it seems like a big case. I went from 9mm 124g bullet to 357 158g JHP. I had to look twice to see the powder in the 357 case. I am loading 8.0g Power Pistol with 8.5 being max. It ought to wake up the neighbors without a problem. My max load for 9mm with 124g bullet is 6.2 and that's max. It shoots that way. I even shot some of the 9mm this morning and it was a handful in the Springfield XDs but it does support +P rounds. I think the 38 sp loads were 5.4 Boy we are having fun now. Craig
