To settle a point of curiosity (mine), I loaded a few 9mm size (.355) 124 grain cast lead bullets into some 38 Special cases. Once done, it was off to the range to see if they would perform adequately. Shooting at a range of about 25 yards, they made a respectable pattern staying well within a minute of steel plate. The main reason behind this test is that I have quite a few more 9mm cast lead bullets on hand than I do 38 Special regulation size (.357-.358) bullets. I don't intend to use this load on a regular basis, but it is nice to know that it can be done!
