High Standard
NO!
the R-107 was made for .22 LR only I believe. the R-106 had dual cylinders for it. I would contact High Standard and find out. But from what I know, High Standard R-107 didn't come with a Magnum Cylinder.
IF the revolver is marked ".22 LR" yes. If it is marked ".22 WMR" or .22 Mag" or " .22 WRF", then NO.
It can.
