I am a lever gun fan and reloader so I would buy it in a heart beat if it was in good shape.
Ammo can be a problem to find, although I have seen it but I don't think anyone has made a run in a long time.
The .307 and .356 are basically rimmed .308 cases with the .356 being necked up to .358. They are not loaded quite as hot as a .358 because most lever guns that were chambered for them won't take the pressure.
Because you would have to use a round nose bullet and since it's a lever action it might do well at 200yrds. but I would not push it past 150 at most. JMO
