Interesting Alex. The actual size for 38 Super is a .356 fmj round nose. Many people are running .355 (9mm, 115 gr.) because it is an easy bullet to find. Hornady recommends a .357 round, although I would want to slug my barrel to find out what the exact tolerance is. IF I could use .357, which is only 1/1000 above the recommended .356 size, then the lead MAY actually spin better as it exits.
Or NOT. in whcich case I just had me a Kaboom!
