If has the magnum cylinder it will.
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.
About $250.
There is no .25 Magnum. There IS a .22 magnum, made by Davis, and a .25 ACP. Value is about $50-$75.

The Model 107 was a single-shot shotgun, not a .22 Magnum rifle. Please send us all the markings directly copied from the rifle so we can properly identify it. We have magazines for virtually all Savage/Stevens products manufactured since 1900. sales@countrygunsmith.net
