I have four solutions for you that none of them require any changing of parts whatsoever:
1. Any .44 Magnum revolver. Can shoot any variety of .44 Magnum, .44 Special, or .44 Russian.
2. Any .357 Magnum revolver. Can shoot any variety of .357 Magnum, .38 Special, or .38 S&W. I am not sure, but maybe also .38 Long Colt.
No on the 38 S&W. It is a larger diameter case. The semi-rimmed 38 Auto and 38 Super will work.
3. Any .32 H&R Magnum revolver. Can shoot .32 H&R Magnum, .32 S&W Long, .32 S&W (Short), and, believe it or not, .32 ACP. Note that .32 ACP actually has a bit of a rim on it. It seems like there is another .32 cartridge that I am forgetting also that will work.
4. Any .22 Long Rifle caliber revolver will work with .22 LR, .22 Long, .22 short, and .22 CB Caps. However, .22 Longs are almost impossible to find now and .22 Shorts are pretty uncommon.
