yes you can , most of my load data book have loads using 158 FP's and HP's , Hornady's 6th edition has loads using there HP-XTP and FP-XTP's , Speer also listed 158gr bullets in there book , I loaded bunny rounds using 9mm cast bullets with Bulleyes ,data I got from an old Handloader Magazine , I don't remember what the charge was but I think it was about the same as you would use in a 38spl ,
