There have been a few revolvers made with interchangeable 22LR and 22 magnum cylinders. However, you cannot add a cylinder unless made for that from the start (22 mag has a larger bore diameter). FIE was the importer, not the maker of arms with their name on it- and they have been out of business for several years. IF you have a "convertable" .22, you may find a cylinder through Numrich, Shotgun News, or similar dealers in used parts.
they both say 22 knock yourself out
Yes, you can shoot .22LR through a .22 Magnum cylinder, provided the firearm is specifically designed for it, such as a convertible revolver that accommodates both cartridges. The .22LR cartridge is shorter than the .22 Magnum, allowing it to fit in the .22 Magnum cylinder. However, using .22LR in a dedicated .22 Magnum firearm that is not designed for it can pose safety risks. Always consult the manufacturer’s guidelines before attempting to use different ammunition types.
Probabably 22LR. Have it checked by a gunsmith.
NEVER attempte to fire ammunition in a weapon it is not chambered for.
