I have considered one myself, as a paper-patch project rifle. They are neat little carbines. Since I hand load and intended to use paper-patched cast bullets, ammo costs didn't/ don't phase me. But, I decided that I did not want to deal with the enbloc clips - they are hard to find and somewhat expensive. I do think that the rifle CAN be single-loaded (as a single shot, by loading a cartridge into the chamber, then closing the bolt on it) WITHOUT using the enbloc clips, but that sort of thing is normally hard on extractors.
So, for now, I've just ditched the idea.
