I have a Dutch Mannlicher, Hembrug 1917. It has been looked at by several gunsmiths and pronounced safe to fire. Problem is ammunition. It is chambered for 6.5x53R, which was used by the Dutch and Romanians for just a few years. Reloading equipment is expensive, as is buying loaded ammunition. Now to my question. Is it possible to rechamber this for a more modern cartridge that is more readily available? What would the options be? Is there another option I am missing? Should I just leave it as it is and never try to use it? ? ? ? I am open to just about any suggestion. Help please.
