I have been experimenting by sizing my LRNFP, 125 grain 38 caliber cowboy boolits to .356 and loading them into my 9mm. They seem to run through my PT99 and 907 slim without any problems. Has anyone else tried this? If so, do you for see any problems? My lead mixture is pretty hard and I don't see any problem with leading at 1000 to 1100fps out of my 9mm.
