I know it does not address the capacity thing. But the accuracy of this little single shot will blow your mind.

Mentioning the Remmy 700 SPS made me think of it. They are like two peas in the same pod in the accuracy department.

regarding multi-shot capability . . . note that the handi rifle has an extractor but not an ejector. It has taken a bit of time practicing (mostly because I am having hand cramp problems) but while not as fast as a bolt gun, it can be reloaded not a lot slower. Oh, and you don't have to chase your brass either. One of the few guns I have that when I take a handful of rounds to the line, I leave it with a handful of empty brass cases (actually I use a shirt pocket or a dump pouch).
