This only applies to revolvers (due to the (generally) different
headspacing between revolvers and autos), but here's a shortish
conversion chart:

      Revolver   Can fire
      --------   --------
      .22WMR     .22WMR, .22lr (with appropos cyl.)

      10mm       .40 Short&Wimpy :-)
      .41Mag     .41Spl (I think it's called .41 Spl; it
                         was developed after the .41Mag)
      .44Mag     .44Spl, .44 S&W, .44 Russian(?)
