MH: I like to play with the 160 grain round nose cast bullet in .356 diameter from CP Bullets. It feeds properly and shoots very well. From the old Lyman manual it can be loaded to duplicate or exceed 38 Spl velocities in the same weight bullet. It's a fun load to shoot and my 9s just keep on tickin' with it. BTW, many of the loads available for that bullet in the 9mm are subsonic but would hit hard. Mikey here.
