If I understand correctly, to reload this gun after firing, you must half-cock it, open it, manually remove the spent shell case and put in a new one, close it, and then cock it fully. How tiresome does that get, either when target shooting or actually out hunting? I don't imagine one ever needs a high rate of fire out of a gun like this, but it still seems like a lot of semi-fiddly things to do with your hands in between shots.
