The .357/.38 run bullets that are .357/8, the 9mm .355/6.... The Ruger BH has two different cylinders, one for .357/.38 and the other for 9mm...
I have three S&W revolvers, a 66-2, a 60-10 and a 649-1 all of which have had the chambers modified so they will also run .38 Super and 9mm via moon clips... So the 66 and 60 will run .357 Magnum, .38 Special, 9x19 and .38 Super. The 649 will not run .357s..
The 2 thousands makes no difference...
